Assertion : HCOOH reacts with H_2 SO_4 to form CO. Reason : H_2...

Assertion : HCOOH\mathrm{HCOOH} reacts with H2SO4\mathrm{H}_2 \mathrm{SO}_4 to form CO. Reason : H2SO4\mathrm{H}_2 \mathrm{SO}_4 is a mild oxidising agent.

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

HCOOH⟶H2SO4H2O+CO\mathrm{HCOOH} \stackrel{\mathrm{H}_2 \mathrm{SO}_4}{\longrightarrow} \mathrm{H}_2 \mathrm{O}+\mathrm{CO} Here, H2SO4\mathrm{H}_2 \mathrm{SO}_4 behaves as a dehydrating agent.
