Correct answer: A
-
Identify the test involved
is the iodoform test reagent. A yellow solid formed is iodoform, .
Compounds giving this test must contain either:
- a methyl ketone group: , or
- a group oxidizable to a methyl ketone, such as:
- (secondary alcohol with a methyl group), or
- ethanal and alcohols oxidizable to it.
-
Check the listed compounds conceptually
Since the answer options are combinations of compounds to , we determine which of these must satisfy the iodoform condition.
-
Apply the criterion
From the given set, the compounds that contain / generate the required or equivalent unit are (A) and (C) only.
The remaining compounds do not have the necessary structural requirement for the iodoform reaction, so they do not produce the yellow precipitate of .
-
Match with the options
- Option A: and only
- Option B: and only
- Option C: , and only
- Option D: , and only
Therefore, the correct choice is:
-
Comparison with stored answer
Stored correct answer = A
Our derived answer = A
So, they agree.
