Step 2:
: Understand Bent Molecular Geometry

Bent molecular geometry occurs when a central atom has two bonding groups and one or more lone pairs of electrons. This causes a deviation from a linear arrangement.

Step 3:
: Determine the Typical Bond Angle

For bent molecular geometry, the standard bond angle is approximately $$109.5^{\circ}$$ to $$120^{\circ}$$.
The exact angle depends on the number of lone pairs on the central atom.

Step 4:
: Factors Affecting Bond Angle

The presence of lone pairs causes repulsion between electron groups, which compresses the bond angle from the ideal tetrahedral angle of $$109.5^{\circ}$$.

Step 5:
: Specific Examples

- Water (H$$_{2}$$O): Bond angle is $$104.5^{\circ}
- Sulfur dioxide (SO_{2}): Bond angle is 119^{\circ}

Final Answer

The bond angle for bent molecular geometry typically ranges from 104.5^{\circ} to 120^{\circ}, with the specific angle depending on the number of lone pairs on the central atom.
