Carbonyl compounds give different oxi...

Carbonyl compounds give different oxidation products with different reagents .Several oxidising agents can be used to oxidise carbonyy compounds .Ammonical silver nitate (tollens reagent ) oxidises aliphatic as well as aromatic aldehydes .
`R-CHO overset("Tollens reagents ") to R-COOh +Ag ` (silver mirror )
strong oxidatising agents like
`KMnO_4 //H^+ ,HNO_3 ,K_2 Cr_2 O_7 //H^+` oxidise
Aldehydes as well as ketons . open chain ketons in oxidation give mixture of two carbonylic acids . oxidation as well as ketons of unsymmetrical ketons takes place according to popoff's rule .According to this rule ` alpha `- carbon whose bond breaks in oxidation always belongs to the alkyl group which has more number of carbons
which of the following is most reactive towards oxidation ?

A

`HCHO`

B

`CH_3 CHO`

C

`CH_3 COCH_3`

D

`CH_3 CH_2CHO`

Text Solution

Verified by Experts

The correct Answer is:
A
HCHO is most reactive due to less steric heinderence and more polarity
