Assertion : Protonation of a carbonyl group increases its electrophilic character.
Reason : Protonation of a carbonyl group involves addition of an electrophile on nucleophilic oxygen.

List-$I$ contains various reaction sequences and List-$II$ contains the possible products. Match each entry in List-$I$ with the appropriate entry in List-$II$ and choose the correct option.

Which statement is incorrect for the given reaction sequence: $CH_3-CN$ $\xrightarrow[(2) H_2O]{(1) CH_3MgBr} X$ $\xrightarrow{2,4-DNP} Y$?

Identify the product $Y$ in the following reaction: $CH_3-CH=CH-CH_2-CHO + H_2 \xrightarrow{Ni} Y$
