Chemistry - CHEMICAL BONDING Question with Solution | TestHub

${\mathrm{SeCl}}_4$ possess see saw geometry, which can be regarded as a distorted trigonal bipyramidal structure, having one lone pair (lp) of electrons in the basal position of the trigonal bipyramidal. Seesaw geometry of ${\mathrm{SeCl}}_4$ molecules arises due to the $s{p}^{3}d$ hybridisation of the central atom. The distortion in shape is due to the presence of one lone pair of electrons.
