1)the answer to the above reaction is B, I was unable to find it in my text book, does this reaction also work the same way with the other halogens or only the Cl2? does it also work with aldehydes the same way ( ie just replace the alpha Hydrogens)?http://i274.photobucket.com/albums/jj243/113zami/orgodd0002.jpg
2) is this group meta or ortho/para directing, and if it's ortho/para directing, is it activating or deactivating.?
I think it should be meta due to the oxygens which are electron withdrawing, am I correct?
3)Between tertiary non allylic and primary allylic carbocation which one is more stable?I know allylic makes you more stable because of resonance but this is primary allylic vs. TERTIARY carbocation, not just a primary one, so I don't know which to choose??
4)Why will tertiary alcohols dehydrate faster than secondary or primary alcohols? Is it because when you dehydrate this is an elimination reaction and elimination reactions always favor the more substituted product?
5)Which substituents will make the benzene more acidic, halogens or meta directing deactivators? I think the halogones should make them more acidic since they're more electron withdrawing than any meta directing group, correct?
6)More intermolecular forces will increase the freezing point, because it's easier to get to the solid state, correct?http://i274.photobucket.com/albums/jj243/113zami/orgodd0005.jpg
7) the correct answer is A but I don't understand why is it not E ? this is how the D2O reaction with benzene is shown in my text (but they don't give a mechanism for it)http://i274.photobucket.com/albums/jj243/113zami/orgodd0004.jpg
that's why I chose E, but is it wrong?!
and also what if the substituent on the benzene was an aldehyde, whould the Deuterium take the place of the H on the aldehyde??
what if there were other substituents (other than aldehyde and ketone) on the benzene with that D2O reagent, how would they react?? I am clueless your help is GREATLY appreciated
