How many electrons should X_(2)H_(4) liberate so that in the new compound X shows oxidation number of -1//2(E.N. X gt H)

Answer»

Solution :Structure of `SO_(3)` or DOT structure of `SO_(3)`
`UNDERSET(1)O=underset(3)underset(O)underset(DARR)Srarrunderset(2)O`
Formal charge on `O^(1)=6-(2+4)=0`
Formal charge on `O^(2)=6-(1+6)=-1`
Formal charge on `O^(3)=6-(1+6)=-1`
Formal charge on `S=6-(4+0)=+2`
