If the dipole moment of HCl is 1.08 D and the bond distance is 1.27 Å , the partial charge on hydrogen and chlorine, respectively are
Options
- A+1.0 and -1.0
- B+0.85 and -0.85
- C+0.356 and -0.356
- D+0.178 and -0.178
Correct answer
B. +0.85 and -0.85
Step-by-step solution
Dipole moment = charge × bond distance 1.08 = charge × 1.27 Charge = 1.08 / 1.27 = 0.85 Since, HCl is electrically neutral, H + and C l - will carry the same charge with opposite sign.
