1. what is the bond angle of nitrogen trichloride (0.5 points) *

109.5
107.8
104.5
120
180

Explanation:

1. Carbon tetrachloride ($CCl_4$) has a tetrahedral geometry with 4 bonding pairs and no lone pairs on C, leading to a bond angle of 109.5°.
2. Nitrogen trichloride ($NCl_3$) has a trigonal pyramidal geometry with 3 bonding pairs and 1 lone pair on N; lone pair repulsion reduces the angle to ~107.8°.

Answer:

1. 109.5
2. 107.8
