Question

In which of the following pairs , both the species are not isostractural ?
A. `NH_(3),PH_(3)`
B. `XeF_(4),XeO_(4)`
C. `SICl_(4),PCl_(4)`
D. Diamond, silicon carbide

Answer 1

Correct Answer - b
(i) Hybridization of `NH_(3) (sigma =- 3, lp = 1)`

(ii) Structure of `XeF_(4)` is square planner.

structure of `XeO_(4)` is tetrahedral

So `XeF_(4)` and `XeO_(4)` are not isostructural
(iii) Structure of `SiCl_(4)` is tetrahedral

Structure of `PCl_(4)^(+)` is tetrahedral

(vi) Both diamond and SiC are isostrucitral because both have terabdral arrangement and atom is `sp^(2)` hybridization
