Which one of the following isomers of PBrCl ₃ have no dipole moment?

Options

  1. AOnly I
  2. BI and ||
  3. CII and III
  4. DOnly III

Correct answer

A. Only I

Step-by-step solution

Symmetrical molecules will have net dipole zero while unsymmetrical will have dipoles. I is symmetrical and have no dipole while II and III have dipoles.
