Answer the following :
(i) Which neutral molecule would be isoelectronic with `CO^(-)`?
(ii) Of Bi (V) and Sb (V) which may be a stronger oxidising agent and why?

Explanation

`ClO^(-)` has 17 +8+1=26 electrons .
A neatual molecule with 26 electrons is `OF_(2)` (`8+2xx9=8+18=26` elctrons).
(ii) On movign down the group, the stability of +5 oxidation, state decreases while+3 oxidation state increases due to inert-pair effct. Thus,+5 oxidaion state of Bi is less stabel thant +5 oxidation state of Sb
Therefore, Bi (V) is stronger oxidising agent then SB(V)
