The angle between the hydrogen atoms in water (H₂O) is slightly less than expected for a tetrahedral shape. This is because of the extra electron repulsion from the lone pairs. This follows VSEPR theory.

What is VSEPR theory ?

The valence shell electron pair repulsion (VSEPR) theory is a model used to predict 3-D molecular geometry based on the number of valence shell electron bond pairs among the atoms in a molecule or ion.

This model assumes that electron pairs will arrange themselves to minimize repulsion effects from one another.

According to VSEPR theory, the order of repulsion is lone pair - lone pair > lone pair - Bond pair > Bond pair - Bond pair

Hence, The angle between the hydrogen atoms in water (H₂O) is slightly less than expected for a tetrahedral shape because of the extra electron repulsion from the lone pairs.
