Question

Predicting Trends a point arrange the following in decreasing (fastest to slowest) rate of hydrating. Explain your arrangement. Arrange of following in order of decreasing acidity (strongest to weakest). Explain your arrangement.

Answer 1

Rate of hydration increases if electron withdrawing groups present near C=O . This creates more electrophilic carbon and H2O ca attack the electrophilic carbon of C=O

Hence order base on this is

A > B > C > D

Carboxylic acid acidity increases if electron withdrawing groups present adjacent to COOH .

D> B > C > A
