Which of the following molecules has "NON ZERO" dipole moment value?

  1. CCl4
  2. HI
  3. CO2
  4. BF3

Answer

(2) HI

Solution

CCl4 (tetrahedral), CO2 (linear) and BF3 (trigonal planar) are symmetrical; their bond dipoles cancel, so = 0.

HI is a heteronuclear diatomic molecule; I is more electronegative than H, so the H–I bond is polar and 0.

Answer: (2)
