Q. The bond angle and dipole moment of water respectively, are
A) $109.5{^\circ},\ 1.84\ D$
B) $107.5{^\circ},\ 1.56\ D$
C) $104.5{^\circ},\ 1.84\ D$
D) $102.5{^\circ},\ 1.56\ D$
Explanation
(c)
[image:4_image189.emf]
In water molecule the $H - O - H$ bond angle is $104.5{^\circ}$ and dipole moment is 1.84 D.
The bond angle of $H_{2}O$ is lower than $109.28''$ due to the presence of two lone pair of electrons on the oxygen atom.
