Question

Benzyl alcohol on treatment with this copper-based catalyst gives a compound ‘A’ which

on reaction with KOH gives compounds ‘B’ and ‘C’. Compound ‘B’ on oxidation with

KMnO4- KOH gives compound ‘C’. Compounds ‘A’, ‘B’ and ‘C’ respectively are ​

Answer 1

The answer is explained below.

Explanation:

Benzyl alcohol on treatment with this copper-based catalyst gives benzaldehyde (A).

Benzaldehyde on reaction with KOH gives compounds benzyl alcohol (B) and potassium benzoate (C).

Answer 2

‘A’, ‘B’ and ‘C’ respectively are Benzaldehyde, benzyl alcohol and potassium benzoate.

• When benzyl alcohol is treated with this copper-based catalyst, it produces Benzaldehyde, which in turn produces benzyl alcohol and potassium benzoate when reacting with KOH. When benzyl alcohol is oxidised with KMnO4- KOH, potassium benzoate is formed.
• Copper-based catalysts are used to convert alcohol into aldehydes. On the reaction to KOH, they undergo self oxidation and reduction to form alcohol and ester.
