The ionic radius of `Cr` is minimum in which of the following compounds ?

A

`K_(2) CrO_(4)`

B

`CrF_(3)`

C

`CrO_(2)`

D

`CrC1_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
Amongst `K_(2) CrO_(4) , CrF_(3) ,CrO_(2) ` and `CrC1_(3) ,Cr` has the maximum oxidation number of + 6 in `K_(2) CrO_(4)` and hence has the minimum ionic radius.
