Which of the following compounds on boiling with KMnO and the subseque...
Explanation:
Benzyl alcohol:
- Benzyl alcohol will give benzoic acid on boiling with KMnO4 and subsequent acidification due to the presence of a benzylic carbon.
Acetophenone:
- Acetophenone will give benzoic acid on boiling with KMnO4 and subsequent acidification due to the presence of an aromatic ring.
Anisole:
- Anisole will not give benzoic acid on boiling with KMnO4 and subsequent acidification because it does not have a reactive hydrogen atom on the aromatic ring. The methoxy group (-OCH3) present in anisole is electron-donating and deactivates the ring towards electrophilic substitution reactions.
Toluene:
- Toluene will give benzoic acid on boiling with KMnO4 and subsequent acidification due to the presence of a methyl group which can be oxidized to a carboxylic acid group.
Therefore, the compound that will not give benzoic acid on boiling with KMnO4 and subsequent acidification is anisole (option c).
