The polarizing power of the following anions \(N^{3-}\),\(O^{2-}\) and \(F^{-}\) follow the order
(A) \(N^{3-} > F^{-} > O^{2-}\)
(B) \(O^{2-} > N^{3-} > F^{-}\)
(C) \(O^{2-} > F^{-} > N^{3-}\)
(D)\(N^{3-} > O^{2-} > F^{-}\)

A

`N^(3-) gt F^(-) gt O^(2-) `

B

`O^(2-) gt N^(3-) gt F^(-)`

C

`O^(2-) gt F^(-) gt N^(3-)`

D

`N^(3-) gt O^(2-) gt F^(-)`

Text Solution

Verified by Experts

The correct Answer is:
D
Greater is the negative charge and size of anion, higher is its polarising power.
