Chemistry - CHEMICAL BONDING Question with Solution | TestHub

(A) SeF₄ and CH₄ have same shape
CH₄ is tetrahedral, but SeF₄ is see-saw (due to lone pair). So incorrect.

(B) I₃⁺ has bent geometry
Central I has 2 bonding pairs + 1 lone pair → bent shape.

(C) PH₅ and BiCl₅ do not exist
Due to inability of heavier atoms to expand coordination/stable hypervalency, both are not stable.

(D) pπ–dπ bonds are present in SO₃
S forms π-bonding with O using pπ–dπ overlap in classical description.

Correct options: B, C, D
