Assertion : CH ₃ COOH but not HCOOH can be halogenated in presence of red P and Cl ₂ . Reason : Both formic acid and CH ₃ COOH are highly soluble in water.

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

The Hell-Volhard-Zelinsky(HVZ) reaction shows halogen substitution at -carbon atom. HCOOH has no -carbon atom and thus does not undergo HVZ reaction.
