Assertion : Carboxylic acids do not give characteristic reactions of carbonyl group. Reason : Carboxylic acids exist as cyclic dimers in solid, liquid and even in vapour state.
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:
Carboxylic acids, being resonance stabilized compounds, exhibit a conjugated structure with the carbonyl group \((-\mathrm{C}=\mathrm{O})\) and hydroxyl group \((-\mathrm{OH})\). They have a resonance hybrid with distributed double bond character, distinguishing them from simple carbonyl compounds. Carboxylic acids exists as dimer even in vapour state upto some extent. So the option (2) is correct.

Assertion : Methanoic acid reduces Tollens' reagent and Fehling solution. Reason : Methanoic acid occurs in a variety of biting and stinging plants and insects.
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:
Methanoic acid is a potent reducing agent because of the presence of the aldehyde group. It has the capability to reduce compounds like Tollen's reagent and Fehling's solution. \(\begin{aligned}\mathrm{HCOOH} & +\underset{\substack{\text { Tollen's } \\\text { reagent }}}{\mathrm{Ag}_{2} \mathrm{O}} \xrightarrow{\text { warm }} \\\mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O} & +\underset{\substack{\text { silver } \\\text { mirror }}}{2 \mathrm{Ag}} \downarrow\end{aligned}\) \(\begin{aligned}\mathrm{HCOOH} & +\underset{\substack{\text { Fehling } \\\text { solution }}}{2 \mathrm{CuO}} \xrightarrow{\Delta} \\& \mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O}+\underset{\text { Red ppt }}{\mathrm{Cu}_{2} \mathrm{O} \downarrow}\end{aligned}\) So the option (2) is correct
