MCQ
Isostructural species are those which have the same shape and hybridization. Among the given species identify the isostructural pairs.
  • A
    $\big[\text{NF}_3 \text{ and BF}_3\big]$
  • B
    $\big[\text{BF}^–4\text{ and NH}^+4\big]$
  • C
    $\big[\text{BCl}_3\text{ and BrCl}_3]$
  • D
    $\big[\text{NH}_3\text{ and No}^–_3\big]$

Answer

  1. $\big[\text{BF}^–4\text{ and NH}^+4\big]$

Explanation:

NF3 is pyramidal whereas BF3 is planar triangular.

BF4 and NH+4 ions both are tetrahedral.

BCl3 is triangular planar whereas BrCl3 is pyramidal.

NH3 is pyramidal whereas NO3 is triangular planar.
