Question

Which of the given compound has highest dipole moment?

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Two identical dipoles cancel each other if they are oriented at an angle of ${180}^{\circ }$ to each other.
Three identical dipoles cancel each other if they are oriented at an angle of ${120}^{\circ }$ to each other.

Resultant dipole moment of (c) is more than other compounds. Here, there is no cancellation of dipole and hence has the maximum dipole moment.
