Question

Statement I The carbonyl carbon is a nucleophilic and carbonyl oxygen is an electrophilic centre.
Statement II The carbon-oxygen double bond is polarised due to higher electronegativity of oxygen relative to carbon.

• A. Both Statement $I$ and $II$ are correct and Statement $II$ is the correct explanation of Statement $I$.
• B. Both Statement $I$ and $II$ are correct and $II$ is not the correct explanation of Statement $I$.
• C. Statement $I$ is correct, Statement $II$ is incorrect.
• D. Statement $II$ is correct, Statement $I$ is incorrect.

Answer 1

Answer: (D)

The carbon-oxygen double bond is polarised due to higher electronegativity of oxygen relative to carbon. The carbonyl carbon is an electrophilic (Lewis acid) and the carbonyl oxygen is a nucleophilic (Lewis base) centre.
