Question

Which bond angle θ would result in the maximum dipole moment for the triatomic molecule YXY
(a) θ = 90°
(b) θ = 120°
(c) θ = 150°
(d) θ = 180°

Answer 1

Answer:

The value of bond angle θ that would result in the maximum dipole moment will be option (a) θ = 90°

Explanation:

The above molecule consists of two atoms X and Y.

The magnitude of dipole moments of two dipoles X and Y is given by,

d = √(X² + Y² + 2XYcosθ)

where θ = angle between them,

At θ = 90°, cosθ = 0

From 90° onwards, the value of cos 90 will become negative, so the value of d will start decreasing after 90°

Hence the value of bond angle θ that would result in the maximum dipole moment will be option (a) θ = 90°

Answer 2

Answer:

a.90

Explanation:

for bond angle 90

would result in the maximum dipole moment for the triatomic molecule YXY
