Which of the molecule has maximum covalent character?
1 \({\rm{NaCl}}\)
2 \({\rm{SiC}}{{\rm{l}}_{\rm{4}}}\)
3 \({\rm{AlC}}{{\rm{l}}_{\rm{3}}}\)
4 \({\rm{MgC}}{{\rm{l}}_{\rm{2}}}\)
Explanation:
Polarisation in the molecule increases with increase of charge and decreases with decrease in size of the cation when the anion is same. Polarisation \( \propto \% \) covalent character the order. So, covalent character is \({\rm{SiC}}{{\rm{l}}_{\rm{4}}}{\rm{ > AlC}}{{\rm{l}}_{\rm{3}}}{\rm{ > MgC}}{{\rm{l}}_{\rm{2}}}{\rm{ > NaCl}}\).

Which of the following is the correct order of stability for the given superoxides
With progressive increase in the size of alkali metal ions,the stability of superoxides increases because the size of superoxide ion is large and large cation can be stabilised more by large anion.Therefore ,the order of stability is \({\rm{K}}{{\rm{O}}_{\rm{2}}} < {\rm{CsO}} < {\rm{Rb}}{{\rm{O}}_2}\)
