Question: Which of the following compounds can show tautomeric isomerism?

Options:

Correct Answer: Acetic acid

Solution:

Acetic acid can exist in keto and enol forms, thus showing tautomeric isomerism.

Which of the following compounds can show tautomeric isomerism?

Which of the following compounds can show tautomeric isomerism?

Step 1: Understand what tautomeric isomerism is. It is when a compound can exist in two different forms that can easily convert into each other.
Step 2: Identify the compound in the question, which is acetic acid.
Step 3: Recognize that acetic acid can exist in two forms: the keto form (which has a carbonyl group) and the enol form (which has a hydroxyl group attached to a double bond).
Step 4: Confirm that the keto and enol forms of acetic acid can interconvert, which is the key feature of tautomeric isomerism.
Step 5: Conclude that since acetic acid can exist in both forms, it shows tautomeric isomerism.
