Assertion : In sodium formate, both the C-bonds have same value 1.27 Reason : Equal bond length is due to the phenomenon of resonance.
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:
Sodium formate, with a linear geometry, displays equal C-O bond lengths 1.27 in the formate ion due to its symmetric structure and even electron density distribution between the identical oxygen atoms. So the option (1) is correct.

Assertion : The carbon atom in carbonyl group is hybridised. Reason :
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:
The bond energy of a carbonyl group is typically around , whereas in the absence of resonance, it is approximately 145.8 . The carbonyl group exhibits resonance, which contributes to its higher bond energy. So the option (3) is correct.
