Question

H₂O has a net dipole moment while BeF₂ has zero dipole moment because 

(a) H₂O molecule is linear while BeF₂ is bent 

(b) BeF₂ molecule is linear while H₂O is bent 

(c) fluorine has more electronegativity than oxygen 

(d) beryllium has more electronegativity than oxygen.

Answer 1

The correct option is : (b) BeF₂ molecule is linear while H₂O is bent 

Explanation:

BeF₂ is linear and hence it has zero dipole moment.

while H₂O is a bent molecule and hence it has a non-zero dipole moment
