Vedclass · Answer

(C) Two species are isostructural if they have the same hybridization and same geometry.$A$. Diamond $(C)$ and Silicon carbide $(SiC)$ both have a tetrahedral structure ($sp^3$ hybridization).$B$. $NH_3$ and $PH_3$ both have a trigonal pyramidal structure ($sp^3$ hybridization with one lone pair).$C$. $XeF_4$ has $sp^3d^2$ hybridization and a square planar geometry,whereas $XeO_4$ has $sp^3$ hybridization and a tetrahedral geometry. Thus,they are not isostructural.$D$. $SiCl_4$ and $PCl_{4}^{+}$ both have $sp^3$ hybridization and a tetrahedral geometry.

List-$I$	List-$II$
$(P)$ $XeF_2$	$(5)$ Trigonal bipyramidal and three lone pairs of electrons
$(Q)$ $XeF_4$	$(3)$ Square planar and two lone pairs of electrons
$(R)$ $XeO_3$	$(2)$ Pyramidal and one lone pair of electrons
$(S)$ $XeO_3F_2$	$(4)$ Trigonal bipyramidal and no lone pairs of electrons

In which of the following pairs,both the species are not isostructural?
