• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (B)

Ortho-nitrophenol is more acidic than meta-nitrophenol because at ortho-position, —NO₂ group shows -M-effect also but at meta-position, —NO₂ group shows only -I-effect.
