Assertion : $\mathrm{CH}_3 \mathrm{COOH}$ but not $\mathrm{HCOOH}$ can be halogenated in presence of red $\mathrm{P}$ and $\mathrm{Cl}_2$.
Reason : Both formic acid and $\mathrm{CH}_3 \mathrm{COOH}$ are highly soluble in water.
  1. both assertion and reason are true and reason is the correct explanation of assertion.
  2. both assertion and reason are true but reason is not the correct explanation of assertion.
  3. assertion is true but reason is false.
  4. both assertion and reason are false.

Solution

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