1.	In view of the signs of `Delta_(r)G^(0)` for the following reactions `PbO_(2)+Pbrarr2PbO,Delta_(r)G^(0)lt0` `SnO_(2)+Snrarr2SnO,Delta_(r)G^(0)gt0` Which oxidation state are more characteristic for lead and tin?A. For lead +2 , for tin +2B. For lead +4 , for tin +4C. For lead +2 lead +2 , for tin +4D. For lead +4 , for tin +2
Answer» Correct Answer - C Negative `Delta_(r)G^(@)` value indicates that `+2` oxidation state is more stable for `Pb^(2)`. Also it is supported by inert pair effect that `+2` oxidation state is more stable for Pb and `+4` oxidation state is more stable for Sn.
