Which bond angle `theta` would result in the maximum dipole moment for the triatomic `YXY`?A. `theta=90^(@)`B. `theta=120^(@)`C. `theta=150^(@)`D. `theta=180^(@)` |
|
Answer» (a) `mu=sqrt(mu_(1)^(2)+mu_(2)^(2)+2mu_(2)mu_(2) cos theta )` If `theta=90^(@)`, `mu` is maximum. Because `cos90^(@)`=0, since, the angle increases from 90to 180, the value of `cos theta` becomes more and more negative and hence resultant decreses. Thus, dipole moment is maximum, when `theta=90^(@)`. |
