Q. Which one of the following will most readily by dehydrated in acidic conditions?
Redox Reactions
Solution:
a. It is $\beta$-keto alcohol, which is easily dehydrated
d. $\beta$-Hydroxy aldehyde or ketones readily undergo dehydration giving $\alpha, \beta$-unsaturated carbonyl compounds, due to the easy loss of acidic $H$ atom at $\alpha- C$ atom. The acidic nature of $H$ atom at $\alpha- C$ atom is due to the presence of an $\bar{e}$-withdrawing carbonyl group
