In proteins, the hydrogen-bonding is present between _.
Correct answer: B. N-H
- A. C-H
- B. N-H
- C. O-H
- D. Cl-H
Explanation
For this case, both Option B and Option C would stand correct; however, the intensity of hydrogen bonding in 'O-H' would be less since it is hindered by the presence of the 'C=O' linked with O-H. The delocalization of electrons, spreading throughout the '-COOH' group, makes Hydrogen Bonding relatively less effective than what is seen with 'N-H.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
