Question 01

Isostructural species are those which have the same shape and hybridisation. Among the given species identify the isostructural pairs.

(a)$\left[N{F}_{3}andB{F}_3\right]$

(b) $\left[B{F}_4^{-}andN{H}_4^{+}\right]$

(c) $\left[BC{l}_{3}andBrC{l}_3\right]$

(d) $\left[N{H}_{3}andN{O}_3^{-}\right]$

Answer 1

Answer: (b).

(a) $N{F}_3$ is pyramidal whereas $B{F}_3$ is planar triangular

(b) $B{F}_4^{-}$ and $N{H}_4^{+}$ ion both are tetrahedral and $s{p}^3$ hybridisation.

(c) $BC{l}_3$ is triangular planar whereas $BrC{l}_3$ is T shaped.

(d) $N{H}_3$ is pyramidal whereas $N{O}_3^{-}$ is triangular planar.
