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

Answer»

`theta=90^(@)`
`theta=120^(@)`
`theta=150^(@)`
`theta=180^(@)`

Solution :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^(@)`.
