Answer:
Explanation:
Strong oxidising agents oxidise toluene and its derivative to benzoic acid .
It is possible to stop the oxidation at the aldehyde stage .
This can be done by using suitbale reagents .
These reagents convert the methyl group to an intermediate thats is difficulct to oxidise further .
Use of Chromyl Chloride ( CrO₂Cl₂ ) .
Chromyl Chloride oxidises methyl group to a chromium complex .
This Chromium complex on further hydrolysis gives corresponding benzaldehyde
This reaction is called Etards Reaction .
