Which of the following does NOT belong to AB4 type molecule:
Correct answer: C. SnCl2
- A. H2S
- B. H2O
- C. SnCl2
- D. PH3
Explanation
SnCl2 does not belong to the AB4 group while the rest of the molecules belong to the AB4 group.H2O and H2S are AB 4 type molecules with two lone pairs. PH3 is an AB 4 molecule with one lone pair. SnCl2 is an AB 3 molecule with one lone pair and two bond pairs.

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.
