P(4)S(3) is isostructural and isosteric ...

`P_(4)S_(3)` is isostructural and isosteric with

A

`Bi_(7)^(3-)`

B

`P_(7)^(3-)`

C

`P_(4)O_(6)`

D

`P_(2)O_(5)`.

Text Solution

Verified by Experts

The correct Answer is:
B
`P_(4)S_(3)` has `15 xx 4 + 16 xx 3` = 108 electrons.
Similarly `P_(7)^(3-)` has `15 xx 7 + 3` = 108 electrons.
So both are isostructural and isosteric (same number of electrons).
