To determine the correct order of bond angles in NH₃, PCl₃, and BCl₃, we can analyze the molecular geometry and hybridization of each molecule step by step. ### Step 1: Analyze NH₃ (Ammonia) 1. **Valence Electrons**: Nitrogen (N) has 5 valence electrons, and each Hydrogen (H) has 1 valence electron. Therefore, NH₃ has a total of: \[ 5 + (3 \times 1) = 8 \text{ valence electrons} \] 2. **Bond Pairs and Lone Pairs**: NH₃ has 3 bond pairs (N-H) and 1 lone pair on nitrogen. ...
