Question

Which of the following compound can show tautomerism ?

Answer 1

Correct option is B.
Correct Answer: Option B

Explanation of correct option:

For tautomerism, there should be at least one $$\alpha-H$$ on the $$sp^3$$ hybridized carbon atom. In option B, there are $$\alpha-H$$, so tautomerism is possible in option B.

Explanation of incorrect options:

In the other options, there is no $$\alpha-H$$ present. So tautomerism is not possible.
