Dear Bhanu,

 

CrO5 IS cromium with four peroxy oxygen and one cordinated oxygen.it is butterfly type structure .central cromium surround with 4 peroxy cyclic oxygen and 1 cordinate oxygen.in this oxidation number of cromium is +6!!!!!!

 

                                      Good Luck!!!!!!!!!

 

                          Plz. approve by clicking 'Yes' given below!!!!!!!!!      Plz.Plz. Plz.!!!!!!!!!

to find out the oxidation number of chromium in the given compound....u've to look into the lewis structure of the compound....

however , by the general method, the O.N. comes out to b +10....but itz not correct....

in itz real structure....one Cr atom is attached  to 4 oxygen atoms....double-bonded with two O-atoms and single bonded with the rest two O-atoms....

oxygen being more electronegative attracts the shared electron towards itself....the double-bonded O-atoms retains 4 electrons while the single-bonded retains 2 electrons.....

in that case...one Cr-atom loses 6 electrons and it retains a positive charge of +6......

so, itz O.N. becomes +6....

   

     hope it aids....

    approve it yss...

There are many questions. On this bases.. Of oxidation cro5 is the tough among themWhy this viod the formula?Why should we draw the structure? There is some bug in chemistry.. ....Why we find oxidation no. Of all others.. Without even drawing lewis structure.. ...
