Assertion : Benzene diazonium salt on boiling with water forms phenol. Reason : \(\mathrm{C}-\mathrm{N}\) bond is polar.

• A

  If both assertion and reason are true and reason is the correct explanation of assertion.
• Correct answer
  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.

Solution

This is the substitution or replacement reaction of benzene diazonium salt, where nitrogen is lost as \(\mathrm{N}_2\) and different groups are introduced in its place.

Hence, the correct answer is option: 'B'.
