In textC textO2 , C-atom is texts textp -hybridised, thus it has linear structure. In textX texte textF2 , Xe is texts textp3 textd hybridised with three lone-pairs of electrons on equatorial positions. This minimises repulsion, hence it has also linear structure.

Q. The pair of species having identical shapes for molecules of both species is

$C F_{4}, S F_{4}$

$X e F_{2}, C O_{2}$

$B F_{3}, PC l_{3}$

$P F_{5}, I F_{5}$

In $C O_{2}$ , C-atom is $s p$ -hybridised, thus it has linear structure. In $X e F_{2}$ , Xe is $s p^{3} d$ hybridised with three lone-pairs of electrons on equatorial positions. This minimises repulsion, hence it has also linear structure.
