The bond angle in H2S is less than H2O. it is due to
Correct answer: B. Greater E.N of oxygen atom
- A. Small size of oxygen atom
- B. Greater E.N of oxygen atom
- C. Oxygen contain two bone pairs of electrons
- D. All of the above
Explanation
Bond angle of H2S(92° )<H2O(104°). As the electronegativity of the central atom decreases, bond angle decreases. In the present case, S is less electronegative than oxygen. Thus bond pairs in H2S are more away from the central atom than in H2O and thus repulsive forces between bond pairs are smaller producing smaller bond angle

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.
