Document Summary
If you have a nonnucleophilic acid (like h2so4, h3po4, ptsoh) (h2so4 is the main one): primary alcohol does not form a carbocation. + cation: basically, never get 1o or ch3, hso4. Always flat if there are 8 pi or more electrons, the molecule can twist and is: nomenclature. Include the catalyst at the end if you are asked to draw the mechanism. I2 doesn"t work because it is endothermic: f2 technically works but it is explosively exothermic so you may get more than you bargained for (aka a fireball!, nitration: add no2. It is anything with a c=o: two basic kinds of carbonyls, class 1, have a leaving group, also known as carboxylic acid or carboxylic acid derivatives. If you have a single carbon carbonyl on a ring, you get fancy nomenclature. If you remove the alcohol, the reaction reverses and you end up with the original carbonyl: exception: cyclic hemiacetals are stable and can be isolated.
