The intermediate compound ‘X’ in the following chemical reaction is

Question

The most suitable reagent for the conversion of \( \text{R-CH}_2\text{-OH} \) to \( \text{R-CHO} \) is:

Answer 1

The given chemical reaction involves the oxidation of toluene to benzaldehyde. This reaction is an example of the Etard reaction, where a methyl group attached to an aromatic ring is selectively oxidized to an aldehyde using chromium(VI) oxide in the presence of carbon disulfide (CS₂).

Step-by-step Explanation:

The initial step involves the reaction of toluene with CrO₂Cl₂ in CS₂ solvent.
This produces an intermediate complex known as the Etard complex.
On hydrolysis of this intermediate complex with water (H₃O⁺), benzaldehyde is formed.

The intermediate compound 'X' in the reaction is the Etard complex, which is a chloro chromium compound.

Correct Option:

The intermediate compound 'X' in the Etard reaction is represented by the correct option:
