What Are the Bond Angles for Bent Molecular Geometry?

In bent molecular geometry, bond angles vary based on the number of bonding and lone pairs. For molecules with 2 bonding pairs and 1 lone pair (e.g., SO2), the bond angle is around 120°, slightly reduced due to lone pair repulsion. For molecules with 2 bonding pairs and 2 lone pairs (e.g., H2O), the bond angle is about 104.5°, much smaller because lone pairs exert stronger repulsion than bonding pairs. These angles are smaller than the ideal angles due to lone pair effects.
