I don't know medically important examples, but nitrocellulose (gun-cotton) is made from nitric acid and cellulose (like from cotton).  I think the nitro-groups replace the OH groups.  The resulting product is an explosive (it can burn without oxygen because it has the required oxidizing groups in the molecule.\n\nThe sugar substitute sucralose (Splenda) is made from sugar where a lot of groups are replaced with chlorines.

Carbohydartes are made of carbon hence the formula C6H12O6 in short these carb are just sugars which are used in making ATP in your cells to provide energy for your body to work. ATP is made in glycoysis, krebs cycle, and ETC transport in your body

The keto is in equilibrium with the enol form. In the enol form, the stereogenic carbon assumes sp2 hybridisation and so loses optical activity.

Food usually consists of carbohydrates and proteins.  Carbohydrate means literally carbon with water and that's what they are made of, carbon, hydrogen and oxygen.  Proteins are made from carbon, hydrogen, oxygen and nitrogen.\n\nWhen you burn something on the stove, the molecules are broken down to their elements, and the hydrogen, oxygen and nitrogen being gasses float away, leaving the carbon behind as a solid.\n\nThe molecules won't ever completely break down, and there will always be minute amounts of other compounds, so the burnt bits won't be pure carbon, but a mess of carbon glued together with other substances.

HCl interacts with pentoses producing furfural or furan-2-carboxaldehyde. The reaction causes a bright pink color. This distinguishes pentoses (sugars containing five carbons) and hexoses (sugars containing six carbons).

A syrupy, water-soluble liquid, C3H6O3, produced in muscles as a result of anaerobic glucose metabolism, and present in sour milk, molasses, various fruits, and wines. A synthetic form of the compound is used in foods and beverages as a flavoring and preservative, in dyeing and textile printing, and in pharmaceuticals.

para-nitroacetophenone, in other words.\n\nMy first inclination is a Friedel-Craft acylation followed by a nitration with nitric acid in sulfuric acid (the nitronium ion). But the addition of the acetyl group would direct the nitro group to the meta position.\n\nMaybe if you nitrate the ring first and reduce the nitro group to an amino group. Then you could Friedel-craft to get the ketone at the para position (with some ortho isomerism). You'd have to find a way to oxidize the amino group to a nitro group ... I don't know how.\n\nAnother method would involve oxidizing toluene with KMn04, to get benzoic acid. You could then esterify the benzoic acid. Using DIBALH (Diisobutyllithium aluminium hydride), you could get an aldehyde (1-phenyl-methanal). You could use a Grignard reagent (methyl magnesium bromide) to get the alcohol with a methyl group added. You could then oxidize the alcohol with PCC to get a ketone. Finally, you could nitrate the ring with nitric acid and sulfuric acid.\n\nI'm not sure if either synthesis is perfect; My second one is long and rather expensive, in terms of reagents. Also, PCC is toxic (chromium) and many of the reducing agents are water sensitive.

chlorine is more electronegative. it is in the '2nd column from right in the periodic table' it is a halogen. the halogen group contains chlorine, flourine, bromine, iodine etc. They are the most electronegative elements of all. nitrogen is placed to the left of chlorine & hence is less negative than Cl. With respect to, say carbon, nitrogen is electronegative [as in CN - cynide] while, in compounds like NO/NO2/ N2O4/ NO3 etc. Nitrogen is electropositive [as compared with oxygen].\n\nu can IM me at YahooMessenger [my ID is fizanaqsh] or email me at my email address which is  fizanaqsh@yahoo.co.in  or even chat via Skype where my ID is homewornetguru, in case u got any more difficulties with chemistry/english/math or physics etc.
