SOLUTION
The correct order of strength of nucleophilies mentioned above is:
CH3?ONa > NaI > NH4?Cl > H2?O
A nucleophile in context of Substitution Nucleophilic reactions (SN1? or SN2?) is stronger when it has more affinity to attach to the positive site.
SN2? reaction also depends on steric factor,so NaI is better nucleophile than MeONa
