Let's solve the question step by step. ### Step 1: Compare NH₃ and PH₃ for bond angle - **NH₃ (Ammonia)** has a trigonal pyramidal shape due to the presence of a lone pair on nitrogen. The bond angle in NH₃ is approximately 107 degrees. - **PH₃ (Phosphine)** has a similar structure but with phosphorus, which is larger and less electronegative than nitrogen. The bond angle in PH₃ is around 93.5 degrees. **Conclusion:** NH₃ has a higher bond angle than PH₃. ...
