Question

the bond angle for a trigonal planar molecule is

Explanation:

In a trigonal planar molecular geometry, the central atom is bonded to three other atoms and has no lone pairs. According to VSEPR (Valence - Shell Electron - Pair Repulsion) theory, the electron - pair repulsions are minimized when the bond angles are \(120^{\circ}\). This is because the three bonding pairs are arranged symmetrically around the central atom in a plane.

Answer:

120 Degrees
