Formic acid is a stronger acid than acetic acid. This can be explained using
1 \(+\mathrm{M}\) effect
2 -I effect
3 + I effect
4 \(-\mathrm{M}\) effect.
Explanation:
Formic acid is stronger acid than acetic acid. This can be explained using + I effect. Acetic acid showing \(+\mathrm{I}\) effect decreases the acid strength as it increases the -ve charge on the carboxylate ion which holds the hydrogen firmly.

In the following reaction, \({{\rm{C}}_{\rm{2}}}{{\rm{H}}_{\rm{5}}}{\rm{OH}}\) acts as
1 electrophile
2 nucleophile
3 dehydrating agent
4 All of these
Explanation:
Since, in the given reaction, \(\mathrm{RO}-\mathrm{H}\) bond breaks, \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\) acts as nucleophile.

Assertion : H-atom of carboxylic group is readily replaced than \(\mathrm{H}\)-atom of alcoholic group. Reason : Resonance gives extra stabilization to carboxylic acid.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Hydrogen atoms in the carboxylic group are typically more readily replaced in chemical reactions compared to the hydrogen atoms in the alcoholic group. This is due to the carboxylate ions stability and good leaving group properties. The alkoxide ion formed from deprotonation of the alcoholic group is less stable making its hydrogen less acidic and less reactive. So the option (1) is correct.
