Assertion: Tautomerism is shown by all nitro alkanes.

Reason: Tautomerism is shown only when mobile

{H}

is present, so

1^{\circ}

and

2^{\circ}

nitro alkanes show tautomerism.

View answer and explanation

Correct option: D

If both assertion and reason are false

Option D (If both assertion and reason are false) is correct because not all nitro alkanes show tautomerism, and the presence of alpha-hydrogens is essential for tautomerism.
