Q. The pair of species having identical shapes for molecules of both species is
A) $CF_{4},\ SF_{4}$
B) $XeF_{2},\ CO_{2}$
C) $BF_{3},\ PCl_{3}$
D) $PF_{5},\ IF_{5}$
Explanation
(b)
In $CO_{2}$, C-atom is $sp$-hybridised, thus it has linear structure. In $XeF_{2}$, Xe is $sp^{3}d$ hybridised with three lone-pairs of electrons on equatorial position. This minimises repulsion, hence it has also linear structure.
