What is the oxidation number of Cr in CrO5 ? plzzz explain in detail.(ans = +6)
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.!!!!!!!!!
here 2 peroxy bonds are presents
the structure is butterfly structure
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...
Dear student,
Its 6 due to the presence of 2 peroxide bonds,....
you can get the oxidatuion number by the structure of CrO5 and i have attached the image also so please check the
image that i have uploaded
