The orientation of electron pairs and the shape of molecule are different in

In water molecule, ${\mathrm{H}}_2\mathrm{O}$ the hybridization of oxygen is ${\mathrm{Sp}}^3.$Thus, the geometry of water molecule must be tetrahedral.

But due to lone pair-lone pair and lone pair-bond pair repulsions the bond angle is reduced to 104° . The structure of ${\mathrm{H}}_2\mathrm{O}$ molecule is a follows as below..

In ${\mathrm{H}}_2\mathrm{O}$ molecule, the orientation of electrons to be “Tetrahedral” but the shape is “ angular”.

Note: In the remaining three molecules, electron pairs and orientation to be same in their shape of molecules.
