Q. The

bond angle in $H_{2}O$ is 104.5. This fact can be best explained with the help of

A) Valence shell electron pair repulsion (VSEPR) theory
B) Molecular orbital theory
C) Presence of hydrogen bond
D) Electronegativity difference between hydrogen and oxygen atoms
Explanation

(a)
The [image:4_image108.emf] bond angle in $H_{2}O$ is $104.5{^\circ}$ due to the presence of two lone pairs of electrons. This fact can be best explained with the help of valence shell electron pair repulsion (VSEPR) theory.
