Which of the following compound has sp3 hybridization:
Correct answer: C. NH3
- A. PCl5
- B. SF6
- C. NH3
- D. HN=NH
Explanation
NH3 has sp3 hybridization. In ammonia, the central nitrogen (N) atom forms three sigma bonds with three hydrogen atoms. The nitrogen's 2s and two of its 2p orbitals hybridize to form four sp3 hybrid orbitals, one of which contains a lone pair of electrons.

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.
