Question

Which bond angle $\theta$ would result in the maximum dipole moment for the triatomic molecule YXY

• A. θ=90^o
• B. θ=120^o
• C. θ=150^o
• D. θ=180^o

Answer 1

The correct option is A

θ=90^o

Resultant dipole moment may be calculated using vectorial method.

$\mu =\sqrt{{\mu }_1{}^2+{\mu }_2{}^2+2{\mu }_1{\mu }_2\cos \theta }$
