Elements of group 15 form compounds in `+5` oxidatin state. However, bismuth forms only one well characterised compound in `+5` oxidation state. The compound is

A

`Bi_(2)O_(5)`

B

`BiF_(5)`

C

`BiCl_(5)`

D

`Bi_(2)S_(5)`

Text Solution

Verified by Experts

The correct Answer is:
B
Stability of + 5 oxidation state decreases top to bottem and +3 oxidation state increases top to bottom due to inert pair effect. Meanwhile compound having +5 oxidation state of Bi is `BiF_(5)`. It is due to smaller size and high electronegativity of fluorine.
