`H_(2)O` is polar, whereas `BeF_(2)` is not because-

Options

A. electronegativity of F is greater than that of O
B. `H_(2)O` involves H-bonding, whereas, `BeF_(2)` is a discrete molecule
C. `H_(2)O` is angular and `BeF_(2)` is linear
D. `H_(2)O` is linear and `BeF_(2)` is angular

Answer

C

Explanation

Because of the linear shape, dipole momens cancel each other in `BeF_(2)` and thus, it is non-polar whereas `H_(2)O` is V-shaped and hence, it is polar.
