The lone pairs in a water molecule cause it to have which shape?

Lone pairs in a water molecule cause it to have non linear shape (angular or bent shape)

Explanation:

The lone pairs of water molecules repel each other in a way that water molecules get angular shape instead of linear shape.

Angular molecules (also called bent or V-shaped) have a non-linear shape. For example, water (H2O), which has an angle of about 105°. A water molecule has two pairs of bonded electrons and two unshared lone pairs.

A 104 degree bond angle, or a V shape
