WebThe mechanism for the electrophilic addition to alkyne is similar to the addition of alkene, with protonation as the first step. For terminal alkyne, if the protonation occurs on … WebCarbonyl function. The carbonyl group is a super function because many common functional groups are based on a carbonyl, including: aldehydes, ketones, carboxylic acids, esters, amides, acyl (acid) chlorides, acid anhydrides. Ester. Esters have a pair of alkyl or aromatic groups attached to a carbonyl + linking oxygen function.
