Question

Assertion : Acetic acid does not undergo haloform reaction.
Reason : Acetic acid has no α hydrogen.
(A) Assertion and Reason are correct and Reason is the correct explanation of Assertion.
(B) Assertion and Reason are correct and Reason isn’t the correct explanation of Assertion.
(C) Assertion is correct but Reason isn’t correct.
(D) Assertion isn’t correct but Reason is correct.

Answer 1

Hint :In the given question firstly we have to define what exactly is the haloform reaction and then when are they feasible and goes through with the process. Now we know that the Haloform test identifies the presence of a $ C{H_3}CO $ group in the aldehydes and ketones.

Complete Step By Step Answer:
The given question statement asks about the validation of the assertion and the reasoning provided in the problem statement. Here we have to go through both of them and then observe whether both are right and if so then whether they validate each other's occurrences or not in the process.
Firstly we have to give the slight explanation of the Haloform Reaction, which is that it is a chemical reaction where a haloform is produced by the exhaustive halogenation of a methyl ketone , in the presence of a base.
Now apart from that we know that the Haloform test identifies the presence of a $ C{H_3}CO $ group in the aldehydes and ketones.
We know that the Acetic acid does not undergo the haloform reaction because in the presence of the $ O{H^ - } $ ions it would act as an acid and thus it doesn’t form the $ CH{X_3} $ haloform.
Acetic acid has three α hydrogens, thus the reason is incorrect.
Therefore we can easily say that the assertion is correct whereas the Reason isn’t.
Option (C) is correct.

Note :
Substrates are broadly limited to methyl ketones and secondary alcohols oxidizable to methyl ketones, such as isopropanol. The only primary alcohol and aldehyde to undergo this reaction are ethanol and acetaldehyde, respectively. 1,3-Diketones such as acetylacetone also give the haloform reaction.
