How will you convert Benzene to Benzoic acid?

Answer:

Benzene can be converted benzoic acid by following steps.

Step 1:

Benzene is converted to toluene by Freidel Craft’s alkylation reaction.

\(C_{6}H_{6}\)→ \([CH_{3}Cl]{AlCl_{3}} C_{6}H_{5}-CH_{3}\)

Benzene Toulene

Step 2:

The toluene is oxidized in the presence of strong oxidizing agent like KMnO4 to produce benzoic acid.

\(C_{6}H_{5}-CH_{3} \overset{KMnO_{4}}{\rightarrow} C_{6}H_{5}COOH\)

Toluene Benzoic acid
