A diatomic molecule has a dipole moment of 1.2 D. If its bond length is equal to 1 0 - 10 m then the fraction of an electronic charge on each atom will be
Options
- A45 %
- B55 %
- C75 %
- D25 %
Correct answer
D. 25 %
Step-by-step solution
µ = q × d 1.2 × 1 0 - 18 = q × 1 0 - 8 c m q = 1.2 × 1 0 - 18 1 0 - 8 = 1.2 × 1 0 - 10 % charge = q e × 100 = 1.2 × 1 0 - 10 4.8 × 1 0 - 10 × 100 = 25 %
