b) But-2-en-2-ol

c) Prop-2-enol

d) Butan-2-ol​

Answer 1

But-3-en-2-ol is a secondary allylic alcohol.

• Secondary allylic alcohols are the allylic alcohols in which the carbon atom is linked with the double bond as well as  to another carbon and also one hydrogen.
• When we oxide the secondary allylic alcohols they turn into α,β- unsaturated ketones
• While in allylic alcohols the hydroxy groups is attached to the saturated carbon which is adjacent to a doubly bonded carbon.
