323976 Assertion :
Carbon-oxygen bond length in
formic acid are 1.23 $A^{\circ}$ and 1.36 $A^{\circ}$
Reason :
Formic acid gives rise to nucleophilic addition reaction.

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:

Resonance in the carboxylate ion limits nucleophilic additions, impeding reactions with $HCN$ , sodium bisulfite and hydroxylamine that aim to replace the carboxylic oxygen. So the option (3) is correct.
