NEET2019ChemistryCarboxylic Acid DerivativesActual
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
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- 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.
