Which bond angle, theta would result in ...

Which bond angle, `theta` would result in the maximum dipole moment for the triatomic molecule `XY_2` ?

A

`theta=90^(@)`

B

`theta=120^(@)`

C

`theta=150^(@)`

D

`theta=180^(@)`

Text Solution

Verified by Experts

The correct Answer is:
A
The dipole moment of two dipoles inclined at an angle `theta` is given by the equation `mu= sqrt(X^(2)+Y^(2)+2XY cos theta) cos90^(@)=0` Since the angle increases from `90^(@)` to `180^(@)` the value of `cos theta` becomes more and more - ve and hence resultant dipole moment decreases. Thus, dipole moment is maximum when `theta=90^(@)`.
