Question

use the lewis structure to predict the molecular geometry of each molecule. ci - b - ci ci × tetrahedral trigonal planar trigonal pyramidal retry

Explanation:

Step1: Count bonding pairs

The central atom B has 3 bonding - pairs with Cl atoms and 0 lone - pairs.

Step2: Apply VSEPR theory

According to the Valence - Shell Electron - Pair Repulsion (VSEPR) theory, when a central atom has 3 bonding pairs and 0 lone pairs, the molecular geometry is trigonal planar.

Answer:

B. trigonal planar
