NEET Chemistry Reactions of Carboxylic Acids MCQ Question
Which of the following statements about the reactions of carboxylic acids is correct?
Carboxylic acids are less electrophilic than aldehydes due to resonance effects.
The acidity of carboxylic acids decreases with the presence of electron-withdrawing groups.
Carboxylic acids cannot form esters in the presence of an alcohol.
Direct attachment of alkyl groups to carboxylic acids increases their acidity.
Correct Answer
Detailed Explanation
Carboxylic acids are indeed less electrophilic than carbonyl carbons due to resonance structures, which stabilizes the carboxylate ion formed upon deprotonation. This is highlighted in the NCERT text that discusses the relative electrophilicity of carboxylic acids compared to aldehydes.
