Vedclass · Answer

(A) Nucleophilicity is the ability of a species to donate an electron pair to an electrophile. For charged species,the nucleophilicity is generally higher than for neutral species. Among the given species,$H_2O$ is a neutral molecule and is the weakest nucleophile. Comparing the anions,$CH_3SO_3^-$ is a very weak nucleophile because the negative charge is delocalized over three oxygen atoms,making it a stable conjugate base of a strong acid. $CH_3CO_2^-$ has the negative charge delocalized over two oxygen atoms,making it a stronger nucleophile than $CH_3SO_3^-$. $OH^-$ is the strongest nucleophile among these as the charge is localized on a single oxygen atom. Thus,the increasing order is $(b) < (c) < (a) < (d)$.

The increasing order of nucleophilicity of the following nucleophiles is: $a. CH_3CO_2^-$,$b. H_2O$,$c. CH_3SO_3^-$,$d. OH^-$
