Assertion : ( ( CH ₃ )₃ CCOC ( CH ₃ )₃ ) and acetone can be distinguished by the reaction with ( NaHSO ₃ ). Reason : ( HSO ₃⁻ )is the nucleophile in bisulphite addition.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of assertion.

Step-by-step solution

HSO ₃⁻ is a bulky nucleophile, hence, cannot attack on sterically hindered ketones.
