Question

In which of the following ionic radii of chromium would be smallest (A) K2CrO4 (B) CrO2 (C) CrCl2 (D) CrF2

Tardigrade Admin · Accepted Answer

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 will be less. Atomic radii decreases with increase in oxidation no.

Q. In which of the following ionic radii of chromium would be smallest

$K_{2} C r O_{4}$

$C r O_{2}$

$C r C l_{2}$

$C r F_{2}$

Oxidation number of $C r$ in options $a, b, c$ and d are $+ 6, + 4, + 3, + 3$ respectively. In given options, (a) has high oxidation number therefore its radii will be less. Atomic radii decreases with increase in oxidation no.
