1 Both \({{\rm{S}}_{\rm{1}}}\,\,{\rm{and}}\,\,{{\rm{S}}_{\rm{2}}}\) are correct and \({{\rm{S}}_{\rm{2}}}\) is a correct explanation of \({{\rm{S}}_{\rm{1}}}\)
2 Both \({{\rm{S}}_{\rm{1}}}\,\,{\rm{and}}\,\,{{\rm{S}}_{\rm{2}}}\) are correct but \({{\rm{S}}_{\rm{2}}}\) is not correct explanation of \({{\rm{S}}_{\rm{1}}}\)
3 \({{\rm{S}}_{\rm{1}}}\) is correct and \({{\rm{S}}_{\rm{2}}}\) is incorrect.
4 \({{\rm{S}}_{\rm{1}}}\) is incorrect and \({{\rm{S}}_{\rm{2}}}\) is correct.
Explanation:
S-1 is correct but S-2 is incorrect since \({\rm{C}}{{\rm{e}}^{{\rm{ + 4}}}}\) is strong oxidising agent.
