H2O has net dipole moment while BeF2 has...

`H_2O` has net dipole moment while `BeF_2` has zero dipole moment because

A

(a) `H_2O` molecule is linear while `BeF_2` is bent

B

(b) `BeF_2` molecule is linear while `H_2O` is bent

C

(c) fluorine has more electronegativity than oxygen

D

(d) beryllium has more electronegativity than oxygen

Text Solution

Verified by Experts

The correct Answer is:
B
`H_2O` have bent structure in which the two O-H bonds are oriented at an angle of `104.5^@` , so water have a net dipole moment whereas `BeF_2` have linear geometry, so the dipole moment of one bond is cancelled by another bond, so it have zero dipole moment.
