1.	How wouldyou account for the following:(i) Of the d4species, Cr2+is strongly reducing while manganese(III) is strongly oxidising.(ii) Cobalt(II)is stable in aqueous solution but in the presence of complexingreagents it is easily oxidised.(iii) The d1configuration is very unstable in ions.
Answer» How would you account for the following: (i) Of the d⁴species, Cr²⁺ is strongly reducing while manganese(III) is strongly oxidising. (ii) Cobalt(II) is stable in aqueous solution but in the presence of complexing reagents it is easily oxidised. (iii) The d¹ configuration is very unstable in ions.

How would
you account for the following:

(i) Of the d⁴species, Cr²⁺
is strongly reducing while manganese(III) is strongly oxidising.

(ii) Cobalt(II)
is stable in aqueous solution but in the presence of complexing
reagents it is easily oxidised.

(iii)
The d¹
configuration is very unstable in ions.
