Calculate the O.N of sulphur, chromium and nitrogen in `H_(2)SO_(5), CrO_(5) "and NO"^(-)3` ion Suggest structure of these compounds.Account for the fallacy if any.

Explanation

(i) O.N of S is `H_(2)SO_(5)`
By conventinal methd the O.n of S in `G_(2)SO_(5) Cr O_(5)` is : 2(+1)+x+5(-2)=0 or x =+8
this is impossible because the maximum O.N of S cannot be more than since is has only six eletron in the velence sheel this fallacy s oversome if we calculate the O.N of S by chemical bonding mehtod
The structure of `H_(2)SO_(5) H-underset(O)underset(||)overset(O)overset(||)S-O-O-H`
(ii) O.B cr in `CO_(5)` according to conventional maximum
this fallacy is removed if we half O.N of Cr by chemical bonding method the structure of ,`CO_(5)` is (ii) O.N `Cr Cro_(5)`
according to conventional maximum O.N of Cr cannot more than six since it chemical bonding configuration this is removed if w calculate O.N Cr by chemical bondng method
