# What is the molecular shape of a molecule that has three electron pairs in which two pairs are shared and one is an unshared pair?

The electron pairs mutually repel each other; and their most stable geometry is as a trigonal plane, with 120""^@ between the pairs. But we describe molecular geometry on the basis of the disposition, the geometry, of atoms, not electron pairs.
An $A {X}_{2} E$ molecule would thus be described as bent, with $\angle X - A - X$ $<$ ${120}^{\circ}$. The angle is compressed somewhat in that the lone pair is closer to the central molecule, and repels the bonding pairs of electron. Species of this type include ozone, ${O}_{3}$, dichlorocarbene, ${\text{CCl}}_{2}$, and nitrite anion, $N {O}_{2}^{-}$. You should look up the actual bond angles observed for these species.
