Question

Assertion: Acetic acid(CH₃COOH) is a monobasic acid.

Reason: Acetic acid has only one replaceable hydrogen atom present which it releases in aqueous solutions as [H⁺].

• A. Both assertion and reason are correct and the reason is the correct explanation of the assertion.
• B. Both assertion and reason are correct but the reason is not the correct explanation of the assertion.
• C. The assertion is correct but the reason is incorrect
• D. The assertion is incorrect but the reason is correct

Answer 1

The correct option is A

Both assertion and reason are correct and the reason is the correct explanation of the assertion.

Explanation for assertion statement:

Monobasic acids are acids that can produce one Hydrogen ion(H⁺) per molecule in an aqueous solution are called monobasic acids. Examples are Hydrochloric acid(HCl), Formic acid or Methanoic acid(HCOOH), etc.

This statement is correct because, Acetic acid(CH₃COOH) can donate only one Hydrogen ion to a base during an acid-base reaction.

Explanation for reason statement:

This statement is correct as-

1. Only one Hydrogen attached to the carboxyl group can be given out as a hydrogen ion.
2. Hence, there is only one replaceable hydrogen atom.

Therefore, both assertion and reason are correct and the reason is the correct explanation for the assertion.

Hence, option (A) is correct.
