In which of the following ionic radii of chromium would

A

`K_(2)CrO_(4)`

B

`CrO_(2)`

C

`CrCl_(3)`

D

`CrF_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Oxidation number of Cr in options a, b, c and d are `+6,+4, +3, +3` respectively.
In given options (a) has high oxidation number therefore its radii with be low. Atomic radii decreases with increase in oxidation no.
