Which statement is incorrect about peptide bond?

Question

 (peptide bond).

Which statement is incorrect about peptide bond?

(a) C - N bond length in proteins is longer than usual bond length of N - C bond.

(b) Spectroscopic analysis shows planar

(c) C - N bond length in proteins is smaller than usual bond length of C - N bond.

(d) None of the above.

Answer 1

Correct option(a) C - N bond length in proteins is longer than usual bond length of N - C bond.

Explanation :

Peptide bond is formed by the reaction of one - COOH group of one amino acid with the NH, group of another amino acid and represented as

As some double bond character is found between C - N bond the bond length of C-N in protein should be smaller than the usual C-N bond.
