Question
Predict the dipole moment of:
a. A molecule $\mathrm{AX}_4$ with square planar geometry.
b. A molecule $\mathrm{AX}_5$ with trigonal bipyramidal geometry.
c. A molecule $\mathrm{AX}_6$ with octahedral geometry.
d. A molecule $\mathrm{AX}_3$ with pyramidal shape.

Answer

  1. Zero.
  2. Zero.
  3. Zero.
  4. It has high dipole moment because dipoles do not get cancelled and there is net dipole moment.
