The largest bond angle in

A

`AsH_(3)`

B

`NH_(3)`

C

`H_(2)O`

D

`PH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
As electronegativity decreases down the group the electron density on central atom of hydride decreases and thus repulsion between bond pair and lone pair of electrons decreases with ultimately decreases `H-M-H` bond angle
Therefore `NH_(3)` having highest bond angle.
