Which bond angle, θ would result in maximum dipole moment for the triatomic molecule YXY?
Options
- Aθ = 90 °
- Bθ = 120 °
- Cθ = 180 °
- Dθ = 150 °
Correct answer
A. θ = 90 °
Step-by-step solution
The resultant dipole moment, μ = μ 1 2 + μ 2 2 + 2 μ 1 μ 2 c o s θ . Therefore, smaller the bond angle, the greater the resultant dipole moment.
