In which one of the following pairs the two speccies have identical shape, but differ in hybridisation?

Options

A. `l_(3)^(-),BeCl_(2)`
B. `NH_(3),BF_(3)`
C. `XeF_(2),l_(3)^(-)`
D. `NH_(4)^(+),SF_(4)`

Answer

A

Explanation

In the ions, halogen atom larger in size like `l_(3)^(-)` undergoes `sp^(3)d` hybridisation giving a linear shape with three lone pairs at equatorial positions. Beryllium chloride has linear structure with sp hybridisation.
