Question

The largest bond angle is in

• A. $AsH_3$
• B. $NH_3$
• C. $H_2O$
• D. $PH_3$

Answer 1

Answer: (B)

$NH_3$

Answer 2

The bond angle in $H_2O$ is about (104.5$^{\circ}$). In $H_2O$, O-atom has two lone pairs. The bond angle in NH3 is about 107$^{\circ}$. In $NH_3$ N-atom has one lone pair. In $AsH_3$ and $PH_3$ the bond angles are nearly 90$^{\circ}$.
