Chemical Bonding and Molecular Structure - Result Question 35
####36. $H_2 O$ has a non zero dipole moment while $BeF_2$ has zero dipole moment because
[1989]
(a) $H_2 O$ molecule is linear while $BeF_2$ is bent
(b) $BeF_2$ molecule is linear while $H_2 O$ is bent
(c) Fluorine has more electronegativity than oxygen
(d) Beryllium has more electronegativity than oxygen.

Solution:
- (b) $BeF_2$ is linear and hence has zero dipole moment while $H_2 O$, being a bent molecule, has a finite or non-zero dipole moment.
