A little help on Organic Chemistry please?

Deep J got it all...Another way  of testing for carbon(IV)oxide is by passing it through lime water(Ca(OH)2).The I.U.P.A.C name for lime water is calcium hydroxide....It turns milky when it is being passed through lime water...This is the cemical equation of the reaction... Ca(OH)2+CO2-CaCO3 + H2O..The milky substance is calcium trioxocarbonate(IV) which is the substance that is used in the production of chalks used in schools...

Is the O-O-O supposed to be an epoxide ring or something?\n\nAnyway, I'm pretty sure the answer to your question is resonance, just like 80% of all organic chem questions.  The double bond and aromatic ring in the first compound help to stabilize an intermediate radical or positive charge on the carbon attached to the Oxygen chain.  The methyl groups in the second compound don't do much to stabilize an intermediate.

I agree with birchardv here...........we need the rest of the problem, and you would learn a lot more if you did the homework yourself.  But do whatever floats your boat.  Add the rest of the problem and I'll get back to you.\n\nOkay Chemist, this problem is really long; if you want a good answer with plenty of steps, I'll need more room.  Email me and I'll send you the solution.

I made flashcards while studying organic chemistry.  Break all the reactions down into the different types of reactions, then make a flashcard for each reaction within all of the types of reactions.  If you want to, you could leave certain details out, like solvents or conditions, and put them on the back to make sure you are remembering them.  I would also write for what cases the reactions would work on each card (eg. primary and secondary alcohols only).  It might be a lot of work to write them out, but it worked for me.  Also, just writing them out will probably help too.  Good luck!!

try asking this in the chemistry section next time....

Lucas Reagent replaces the OH group by a Cl group.\nTherefore CH3-C5H8-OH + HCl -> CH3-C5H8-Cl + H2O

2KOH=>K(2)O+H(2)O\n\nFeO+C=>CO+Fe\n\nCa+2AlCl=>CaCl(2)+2Al\n\nP(2)O(5)+3H(2)O=>2H(3)PO(4)\n\n2KI+Pb(NO3)2=>2KNO(3)+PbI(2)

Chemistry of carbon compounds is known as organic chemistry. Organic chemistry encompasses study of all carbon-hydrogen compounds. These are also called hydrocarbons. Inorganic carbon chemistry is the study of oxides, nitrides and allotropes of carbon.\n\nThere are many differences between organic and inorganic compounds. Organic compounds are mostly insoluble in water. They have low melting points and exist by forming covalent bonds. Inorganic compounds on the other hand usually dissolve in water and have high melting points. Inorganic compounds can be formed due to either ionic or covalent bonds. Another characteristic of organic compounds is that they are inflammable.\n\nCarbon has 6 protons, 6 neutrons and 6 electrons. Its chemical symbol is 12C 6. Its electronic configuration is 2 electrons in the K-shell, and 4 electrons in the L-shell. In principle it should either give up or borrow 4 electrons while forming compounds. But it doesn’t form ionic bonds at all. It likes to share its four electrons with other atoms and form covalent bonds instead. Carbon covalent bonds are the strongest in nature.\nWe might expect that a carbon atom to form three bonds of one kind using the p orbital electrons and one bond of another kind using the s orbital electron. But this does not happen!! The one 2s and three 2p orbitals mix together and give rise to four new altogether different types of orbitals. This is called  hybridization and is seen only in carbon atom. The four orbitals are at an angle of 109028’. This is called tetrahedral or sp3 (pronounced as sp three) type of hybridization. There are sp2 and sp types of hybridization also.

Organic compounds have carbon in them.  Examples would be methane, sugar, alcohol, etc.\n\nInorganic compounds are all other compounds.  Examples would be salts (such as NaCl or MgCl2), water, etc.

If organic chemistry is your thing, download ITunes and look up Chem 241,242, and 243 from Jean-Claude Bradley.  He goes through everything at a good pace.  If you don't wanna deal with ITunes, try going to chem241.blogspot.com and getting the flash versions, they have sound and picture just like the ipod videos from itunes.\n\nFor other stuff from that class, go to chem241.wikispaces.com for other links and downloads and such.  His class is open to everyone, even though he's at Drexel university.  Whenever you are asked on the wiki, the username is coas, password codrexelas.

The most important concept of organic chemistry is "the interaction of filled and empty orbitals is stabilising!" Keep that in mind and you will be fine.
