Question

why aromatic acyl chloride are much less reactive than aliphatic acyl chloride?Explain.
​

Answer 1

Answer:

1. Acid chlorides are the most reactive of the derivatives of carboxylic acids.

2. But aromatic acid chlorides are much less reactive than aliphatic acid chlorides due to the electron-donating resonance effect (+R effect) of benzene ring due to which the electron deficiency of aromatic acyl carbon decreases.

3. That is the reason aromatic acyl chloride is much less reactive than aliphatic acyl chloride.
