Match the following columns :

Column-I	Column-II
(a) ${\mathrm{ClF}}_2^{-},$${\mathrm{ClF}}_2^{+}$	(p) Square pyramidal
(b) ${\mathrm{IO}}_2{\mathrm{F}}_2^{-},{\mathrm{F}}_2\mathrm{SeO}$	(q) See-saw and pyramidal shaped respectively
(c) ${\mathrm{IOF}}_4^{-},{\mathrm{XeOF}}_2$	(r) Linear and bent shaped respectively
(d) ${\mathrm{BrF}}_5,{\mathrm{XeOF}}_4$	(s) Square pyramidal and T-shaped respectively
	(t) Both ${\mathrm{sp}}^3{\mathrm{d}}^2$

Hybridization of ${\mathrm{ClF}}_2^{-}$ with ${\mathrm{sp}}^3$ (three lone pairs of Cl at three corners and two F at vertices). This gives it a linear shape.
${\mathrm{ClF}}_2^{+}$ is hybridised to form ${\mathrm{sp}}^3$ (two bond pairs with F and two lone pairs on Cl). As a result, it is curved.
The two free valence electron lone pairs and the Xe-O bond domain occupy the trigonal plane, while the Xe-F bond domains are parallel to one another and perpendicular to the trigonal plane, according to the geometry of ${\mathrm{XeOF}}_2$, which is compatible with a trigonal bipyramidal, AX₂YE₂, VSEPR arrangement.
Trigonal pyramidal is how ${\mathrm{IO}}_2{\mathrm{F}}_2^{-}$ is shaped (Sea-saw)
