`H_2O` is dipolar, whereas `BeF_2` is not. It is because:-

A

the electronegativity of F is greater than that of O

B

`H_2O` involves hydrogen bonding whereas `BeF_2` is a discreate molecule

C

`H_2O` is linear and `BeF_2` is angular

D

`H_2O` is angular and `BeF_2` is linear

Text Solution

Verified by Experts

The correct Answer is:
D
The structure of `H_2O` is angular or V-shape and has `sp^3` hybridisation and `104.5^@` bond angle . Thus, its dipole moment is positive or more than zero.

But in `BeF_2` , structure is linear due to sp hybridisation (`mu`=0)

Thus, due to `mu` gt 0 , `H_2O` is dipolar and due to `mu`=0 .`BeF_2` is non -polar.
