Biomolecules - Result Question 35
####35. For $-C-\ddot{N} H-$ (peptide bond)
[2001]
Which statement is incorrect about peptide bond?
(a) $C-N$ bond length in proteins is longer than usual bond length of the $C-N$ bond
(b) Spectroscopic analysis shows planar structure of the $-C-NH-$ group
(c) $C-N$ bond length in proteins is smaller than usual bond length of the $C-N$ bond
(d) None of the above
Show Answer
Solution:
- (a) Due to resonance $C-N$ bond in protein acquires double bond character and is smaller than usual $C-N$ bond.
