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

A

`H_2O` is angular and `BeF_2` is linear

B

the electronegativity of F is greater than that of O.

C

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

D

`H_2O` is linear and `BeF_2` angular.

Text Solution

Verified by Experts

The correct Answer is:
A
`H_2O` is dipolar whereas `BeF_2` is not because `H_2O` is angular (with `sp^3`-hybridisation and two lone pairs on O-atom) and `BeF_2` is linear (with sp-hybridisation)
