An aldehyde is either a functional group consisting of a terminal carbonyl group or a compound containing a terminal carbonyl group.\n\nCommon reactions\naldehydes react with alcohols and an acid or base to a hemiacetal, the hemiacetal and alcohol and more acid catalyst further react to an acetal and water \nSimple hemiacetals are usually unstable, although cyclic ones such as glucose do exist. Acetals are stable, but these revert to the aldehyde in the presence of aqueous acid. \nTreating aldehydes with oxidizing agents such as potassium permanganate, nitric acid, chromium(VI) oxide or acidified potassium dichromate), will yield a carboxylic acid. \nTreating aldehydes with Tollens' reagent (which is prepared by adding a drop of sodium hydroxide solution into silver nitrate solution to give a precipitate of silver(I) oxide, and then adding just enough dilute ammonia solution to redissolve the precipitate in aqueous ammonia to produce [Ag(NH3)2]+ complex) will convert aldehydes to carboxylic acids without attacking carbon-carbon double-bonds. This reaction is also known as the silver mirror test. \nAldehydes can react with water (under acidic or basic conditions) to form hydrates, R-C(H)(OH)(OH), although these are only stable when strong electron withdrawing groups are present, as in chloral hydrate. The mechanism is identical to hemiacetal formation. \nAldehydes can react with HCN to form cyanohydrins, R-C(H)(OH)(CN). \nTreating an aldehyde with a Grignard reagent can yield an alcohol with a substituted group from the Grignard reagent. \nTreating aldehydes with NH3 derivatives (like NH2OH, H2NNH2, 2,4-dinitrophenylhydrazine) will result in the formation of an oxime or hydrazone. This is classed as an addition-elimination reaction or addition-condensation reaction. If the simple hydrazone (RCH=NHNH2) of an aldehyde is heated with a base such as KOH, the terminal carbon is fully reduced via the Wolff-Kishner reaction to a methyl group. The Wolff-Kishner reaction may be performed as a one-pot reaction, giving the overall conversion RCH=O → RCH3. \nReaction of aldehydes with reducing agents such as magnesium gives diols in a Pinacol coupling reaction \nThe Wittig reaction takes aldehydes to alkenes and the Corey-Fuchs reaction takes aldehydes to alkynes both with a triphenylphosphine reagent. The Corey-Chaykovsky reagent is a sulfonium ylide which convert aldehydes to epoxides. \n\nExamples of Aldehydes:\n\nMethanal (Formaldehyde) \nEthanal (Acetaldehyde) \nPropanal \nButanal \nPentanal \nGlucose \nBenzaldehyde

NaBH4 functions as BH4-, which donates a hydride (a hydrogen with a negative charge) to the aldehyde or ketone that you're working with. The product is a sodium salt/alkoxide. Water or HCl (acid) will protonate the alkoxide to generate the alcohol that you need. \n\nThe gas formed was probably hydrogen, from when the HCl reacted with the Sodium borohydride.

Last year my nerdy friends and I made Christmas ornaments out of test tubes.  We got ahold of some stuff called Tollen's reagent that's used to perform the "silver mirror test".  That's used to distinguish between aldehydes and ketones because mixing Tollen's reagent with an aldehydes causes it to coat the vessel like a silver mirror, but nothing happens with ketones.  We mixed the Tollen's with an aldehyde and shook the test tubes until the mirrors formed, then decorated them.

Removing the OCH3 group leaves the framework: CH3CH2CHO and aldehyde! Since only one methoxy group is added the compound is a hemiacetal.

Phenol formaldehyde resin\nFrom Wikipedia, the free encyclopedia\nJump to: navigation, search\nThe earliest commercial synthetic resin is based on a Phenol formaldehyde resin with the commercial name Bakelite, and is formed from a elimination reaction of phenol with formaldehyde. Phenol is reactive towards formaldehyde at the ortho and para sites (sites 2, 4 and 6) allowing up to 3 units of formaldehyde to attach to the ring. This forms a hydroxymethyl phenol, which is not usually isolated in novolacs but is found in resoles (see below). The hydroxymethyl group is capable of reacting with either another free ortho or para site, or with another hydroxymethyl group. The first reaction forms a methylene bridge, and the second forms an ether bridge.\n\nPhenol formaldehyde resins, as a group, are formed by a step-growth polymerization reaction which may be either acid or base catalysed. The pathway the reaction follows varies depending on the catalyst type used.

"Parfum" is the French word for perfume, so this is just a snooty way for the deodorant maker to make the ingredient list seem more sophisticated and special.\n\nParfum is generally not an alcohol itself, but there may be some alcohol used as a solvent to get it into the mixture that makes up your deodorant.

Because if it is made of plastic, Plastic is a product of petroleum.\n\nYou will probably be surprised to know that a plastic bottle is made from the same petrochemical as the fiber we call polyester!\n\nAll plastic products, many of the materials used to make the clothes you wear, or the carpet you walk on, plus hundreds of the other products we take for granted, are made from petrochemicals. As the name implies, a main ingredient in petrochemicals is oil. \n\nPlastic: Any of various complex organic compounds produced by polymerization, capable of being molded, extruded, cast into various shapes and films, or drawn into filaments used as textile fibers. \n-- Webster's Dictionary\n\nThat's an interesting definition, you may be thinking, but really -- how is plastic made? What's involved in the plastics manufacturing process? \nThe Basics of Plastic Manufacturing \n\nThe term "plastics" encompasses organic materials, such as the elements carbon (C), hydrogen (H), nitrogen (N), chlorine (Cl) and sulfur (S), which have properties similar to those naturally grown in organic materials such as wood, horn and rosin. Organic materials are based on polymers, which are produced by the conversion of natural products or by syththesis from primary chemicals coming from oil, natural gas or coal. \n\nThe plastic manufacturing process begins by heating the hydrocarbons in a "cracking process." Here, in the presence of a catalyst, larger molecules are broken down into smaller ones such as ethylene (ethene) C2H4, propylene (propene) C3H6, and butene C4H8 and other hydrocarbons. The yield of ethylene is controlled by the cracking temperature and is more than 30% at 850°C and such products as styrene and vinylchloride can be produced in subsequent reactions. These are then the starting materials for several other types of plastics. Therefore, this process results in the conversion of the natural gas or crude oil components into monomers such as ethylene, propylene, butene and styrene. \n\nThese monomers are then chemically bonded into chains called polymers. Different combinations of monomers yield plastic resins with different properties and characteristics. Each monomer yields a plastic resin with different properties and characteristics. Combinations of monomers produce copolymers with further property variations. \n\nThe resulting resins may be molded or formed to produce several different kinds of plastic products with application in many major markets. The variability of resin permits a compound to be tailored to a specific design or performance requirement. This is why certain plastics are best suited for some applications while others are best suited for entirely different applications. For instance, impact strength measures the ability of a material to withstand shock loading. Heat resistance protects the resin from exposure to excessive temperatures. Chemical resistance protects the resin from breakdown due to exposure to environmental chemicals. \n\nSome examples of material properties in plastic product applications are: \n\nHot-filled packaging used for products such as ketchup \nChemical-resistant packaging used for products such as bleach \nImpact strength of car bumpers \n\nThe Structure of Polymers \n\nPolymers are created by the chemical bonding of many identical or related basic units and those produced from a single monomer type are called homopolymers. These polymers are specifically made of small units bonded into long chains. Carbon makes up the backbone of the molecule and hydrogen atoms are bonded along the carbon backbone. \n\nPolymers that contain primarily carbon and hydrogen are classified as organic polymers. Polypropylene, polybutylene, polystyrene and polymethylpentene are examples of these.\n\nEven though the basic makeup of many polymers is carbon and hydrogen, other elements can also be involved. Oxygen, chlorine, fluorine, nitrogen, silicon, phosphorous and sulfur are other elem

I'm sorry I don't know what it is made of, but I know it is expensive and there is not really a huge difference between it and the other similar products offered that I have tried. If you are going to get him something try to find the odor-repellent kind that is made durable. ( Many of the things sold are of great material but not put together well and most synthetic fibers retain odors so that they can only be worn once before stinking to high heaven.)\nColumbia has some good products.

Yes it is illegal.  The major component of formaldehyde is formalin that can be mixed with alcohol and used as a preservative.  Formaldehyde is extremely carcinogenic, fumes and all.

I won't answer this completely, because it looks very much like homework. \n\nI will say that an Aldehyde and a Ketone will yeild different degree alcohols. Reactions that yeild an primary alcohol from an Aldehyde would yeild a secondary alcohol from a ketone. Reactions that yeild an secondary alcohol from an Aldehyde would yeild a tertiary  alcohol from a ketone.
