B

4.18 debye

C

4.8 debye

D

0.48 debye

Text Solution

Verified by Experts

The correct Answer is:
C
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.
