Question

In which of the following the bond angle is maximum?

• A. $N{H}_3$
• B. $N{H}_4^{+}$
• C. $PC{l}_3$
• D. $SC{l}_2$

Answer 1

The correct option is B $N{H}_4^{+}$

The bond angle in $N{H}_3$ is ${107.5}^0$
The bond angle in $N{H}_4^{+}$ is ${109.5}^0$
The bond angle in $PC{l}_3$ is are ${120}^0$ (equitorial bond angle) and ${90}^0$ (axial bond angle)
The bond angle in is $SC{l}_2$ is ${120}^0$
So the highest bond angle is there for $N{H}_4^{+}$
Hence option $B$ is correct.
