Question

which one cannot be oxidised to give carboxylic acid?​

Answer 1

Answer:

Hence, acetone on oxidation will not give carboxylic acid with same number of carbon atoms.

Answer 2

Answer:

Carboxylic acids (HCOOH) have the C-1 at +3 oxidation state, To oxidise further to +4, they need to break the C1-C2 bond and attach another hetero atom to C1. this is only possible if they form CO2 on oxidation.

Explanation:

This is only possible if they form CO2 on oxidation.

$CH _{3}$ $C$≡$N cannot be oxidized to$ $CH_{3} COOH$

With aldehydes and alcohols, CH 3 COCH 3 does not have an ox disable hydrogen atom.

As a result, it undergoes oxidative cleavage under harsh circumstances, yielding acetic and formic acid (after cleavage of C-C bond).

When alcohols are oxidised, aldehydes, ketones, or acids with the same number of carbon atoms are formed.

Similarly, oxidation of aldehydes results in the creation of acids with the same amount of carbon atoms.

As a result, when acetone is oxidised, it does not produce carboxylic acid with the same number of carbon atoms.
