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

Options

A. `NH_(3)` and `BF_(3)`
B. `BF_(4)^(-)` and `NH_(4)^(+)`
C. `BCl_(3)` and `BrCl_(3)`
D. `NH_(3)` and `NO_(3)^(-)`

Answer

A

Explanation

a) `NF_(3)` is pyramidal whereas `BF_(3)` is planar triangular.
b) `BF_(4)^(-)` and `NH_(4)^(+)` ion both are tetrahedral and `sp^(3)` hybridisation.
c) `BCl_(3)` is triangular planar whereas `BrCl_(3)` is T shaped.
d) `NH_(3)` is pyramidal whereas `NO_(3)^(-)` is triangular pianar.
