Which statement is incorrect about peptide bond?

A.C - N bond length in proteins is longer than usual✓ Correct

B.Spectroscopic analysis shows planar structure of

C.C–N bond length in proteins is smaller than usual

D.None of the above

Explanation

It is due to the resonance that the C-N bond length of amino-acid becomes smaller than the C-N single bond length. The resonance structure is shown below- Thus, the correct option is (a) C-N bond length in proteins is longer than usual bond length of C-N bond
