Chemistry - Carbonyl compounds Question with Solution | TestHub

Question Explanation:

The question asks to identify the compound(s) that do not undergo the haloform reaction.

Concept :

This question is based on haloform reaction and the presence of methyl ketone or oxidizable secondary alcohol

Solution:

The haloform reaction is shown by compounds containing a methyl ketone group (R–CO–CH₃ ) or by secondary alcohols of the type R–CH(OH)–CH₃ , which can be oxidized to methyl ketones under the reaction conditions.

α-halogenated carbonyl gives haloform ration.

Among all options, Option (3) acetophenone and Option (4) 2,2- Diiodo ethanal can give haloform reaction.

Final Answer: Option (A) & (B)
