49. This reaction is called

(1) Darkin reaction
(2) Chichibabin reaction
(3) Jone's oxidation
(4) Etard's reaction

Correct Answer: (4) Etard's reaction

Solution:The Etard reaction is a chemical reaction that involves the direct oxidation of an aromatic or heterocyclic bound methyl group (CH₃) to an aldehyde using chromyl chloride (CrO₂Cl₂). Etard reaction involves conversion of alkyl benzene or compounds having alkyl group attached to heterocyclic ring in to aromatic aldehydes. This is one of the finest methods to prepare ben zaldehyde. In this reaction toluene is treated with Chromyl chloride in presence of CS2 or CCI₄ to form Etard complex which on hydrolysis, benzaldehyde is obtained.

In this reaction CrO2Cl2 attacks on the alkyl group connected to the ring to form unsaturated intermediate which in turn undergoes 2-3 sigmatropic rearrangement to form chromium complex. This complex hydrolyses so easily to give benzaldehyde.
