Vedclass · Answer

(B) Nucleophilicity is the ability of a species to donate an electron pair to an electrophile. In general,for species with the same nucleophilic atom,the nucleophilicity follows the basicity order. The basicity order is: $CH_3O\Theta > \Theta OH > CH_3COO\Theta > CH_3SO_3\Theta > H_2O$. $CH_3O\Theta$ is a stronger base than $\Theta OH$ due to the $+I$ effect of the methyl group. $CH_3COO\Theta$ is a weaker base due to resonance stabilization of the negative charge. $CH_3SO_3\Theta$ is a very weak base due to extensive delocalization of the negative charge. $H_2O$ is a neutral molecule and the weakest nucleophile among the given species. Therefore,the correct order of decreasing nucleophilicity is $CH_3O\Theta > \Theta OH > CH_3COO\Theta > CH_3SO_3\Theta$.

The order of decreasing nucleophilicity of the following is:
