The bond angle and dipole moment of water respectively are `:`

A

`102.5^@`, `1.56D`

B

`107.5^@, 1.56D`

C

`109.5^@, 1.84D`

D

`104.5^@, 1.84D`

Text Solution

Verified by Experts

The correct Answer is:
D
The steric number of O atom in water is `2+2=4`. Thus, `H_2O` has tetrahedral geometry but angular shape. Due to lone pair-lone pair repulsion, the bond angle is reduced from `109.5^@` to `104.5^@`. Due to contribution of electronic dipoles and bond dipoles, it has high dipole moment.
