Answer
A molecule with seesaw molecular geometry has a bond angle of 90° and 120°.
Seesaw is a type of molecular geometry where there are four bonds attached to a central atom.
Bond is observed in the shape of playground seesaw that is why it is known as a seesaw bond.
Four bonds attached to the central bond formed results as tetrahedral or square planar geometry.
In see-saw, shape maximizes the bond angle of the lone pair and the other atoms in the molecule.
lone pair in the equatorial position offer 120 and 90-degree bond angles whereas bond angle will be 90-degree bond angles if placed at axial position.
