In a polar molecule , the ionic charge is `4.8 xx 10^(-10)` esu. If the interatomic distance is `1 Å` unit, then the dipole moment is

Options

A. 41.8 debye
B. 4.18 debye
C. 4.8 debye
D. 0.48 debye

Answer

C

Explanation

Given ionic charge ` = 4.8 xx 10^(-10)` e.s.u. and ionic distance ` = 1A^@ = 10^(-8) cm`.
We know that dipole moment = ionic charge `xx` ionic distance `= 4.8 xx 10^(-10) xx 10^(-8)`
` = 4.8 xx 10^(-18)` e.s.u. per cm = 4.8 debye.
