Current Question (ID: 8052)

Question:

$\text{Which of the following species has a bond angle of } 120^{\circ}?$

Options:

1. $\text{SF}_6$
2. $\text{NCl}_3$
3. $\text{BCl}_3$ (Correct)
4. $\text{PH}_3$

Solution:

$\text{HINT: Molecule having } sp^2 \text{ hybridization has } 120^{\circ} \text{ degree bond angle.}$ $\text{Explanation:}$ $\text{BCl}_3 \text{ is } sp^2 \text{ hybridized and its shape is trigonal planar. Hence, the bond angle is } 120^{\circ}. \text{ The structure is as follows:}$ $\text{PH}_3 \text{ is drago compound and its bond angle is } 90^{\circ}. \text{ SF}_6 \text{ hybridization is } sp^3d^2 \text{ and } \text{NCl}_3 \text{ is } sp^3 \text{ and bond angle is } 107^{\circ}$
