The correct options are
A XeF2,CO2
B I−3,HgCl2
C OCl−,CO
D SO2,OCl2
(a) Both XeF2 and CO2 are linear in shape.
XeF2 undergoes sp3d2 hybridization and and CO2 undergoes sp hybridization.
(b) Both I−3 and HgCl2 are linear in shape.
I−3 undergoes sp3 hybridization and HgCl2 undergoes sp hybridization .
(c) Both OCl− and CO are linear in shape.
OCl− undergoes sp3 hybridization and CO undergoes sp hybridization.
(d) Both SO2 and OCl2 are angular in shape.
SO2 undergoes sp2 hybridization and OCl2 undergoes sp3 hybridization.
Thus, all the four options are correct.
