Question

What is the main reactant in the prepartion of benzaldehyde by Etard's reaction? (A) Toluene (B) Ethyl benzene (C) Benzoyl chloride (D) Sodium benzoate

Tardigrade Admin · Accepted Answer

Toluene can be oxidized to benzaldehyde with a solution of chromyl chloride

(C r O_{2} C l_{2})

in

C S_{2}

or

CC l_{4} .

This is known as Etard's reaction.

Solution

Further oxidation of benzaldehyde to benzoic acid is avoided by protection of carbonyl group.
