Question
Carbon tetrachloride and ammonia have dipole moment values. Explain.
Solution
Carbon tetrachloride molecule has zero dipole moment even though C and Cl have different electronegativities and each of the C - Cl bond is polar and has some dipole moment. This is because the individual dipole moments cancel out because of the symmetrical tetrahedral shape of the molecule.
On the other hand, ammonia is a polar molecule having resultant dipole moment 1•49 D.
The molecular dipole moment of ammonia molecule is the resultant of three polar N – H bonds oriented in space at an angle of 107° with respect to each other.
