AIIMS
AIIMS 1999
Chemical Bonding and Molecular Structure
A
$HI$
9%
B
$H_2O$
60%
C
$NH_3$

D
$SO_3$
6%
Solution:
Dipole moment in the molecule depends upon the charge and the distance between the charges.
As oxygen is more electronegative than nitrogen, iodine or sulphur, it will have greater dipole moment.
