1well i know abt it.......but i m asing why ans is not coming by the normal way?
wat is the O N of
1) Cr in CrO5
2)S in H2SO5
why is with normal way of finding ON the ans is not coming

1The best way is to draw the structures..you wnt get a wrong answer that way...try these questions by making structures.

29For these questions..u need to know the Structure for finding the Oxidation number...
CrO5 --- Cr is in +6 oxidation state..
H2SO5---S is in +6 oxidation state
for solving these questions u may see the method in this thread..

29we cannot find this by normal way ..coz in normal way u take Oxidation state of O as -2 but it's not true for all oxtgen atoms here as we have peroxy linkages in which Oxidation state of oxygen is -1 ..so to find the oxidation state in this cases u have u use the method given in the link in abv post
1we cannot do this by the normal method becoz in both the compounds there are peroxy bonds ..
In CRO5 there are 4 peroxy bonds and in H2SO5 one peroxy bond .....for a peroxy bond u need to take -1 instead of oxygen's -2 ... that will give you the answer ...
