Question

Which of the following types of alcohol contain a bond between sp^2 hybridised carbon and OH group?

(a) Primary allylic alcohols

(b) Secondary allylic alcohols

(c) Tertiary allylic alcohols

(d) Vinylic alcohols

I have been asked this question in a job interview.

This question is from Alcohols, Phenols and Ethers Classification in chapter Alcohols, Phenols and Ethers of Chemistry – Class 12

Answer 1

Right answer is (d) Vinylic alcohols

For explanation I would say: Allylic alcohols are those in which OH group is attached to a sp^3 hybridised carbon adjacent to a C-C double bond, i.e., an allylic carbon. Whereas, vinylic alcohols contain OH group attached directly to a C-C double bond.
