The correct order of the rate of the reaction for the following reaction with respect to nucleophiles is:
$$CH_{3}Br + Nu^{\ominus} \rightarrow CH_{3}Nu+Br^{\ominus}$$
The reaction $$CH_3Br + Nu^- \to CH_3Nu + Br^-$$ is an SN2 reaction. The rate depends on the nucleophilicity of $$Nu^-$$.
Nucleophilicity order:
$$^-OH$$ is a strong nucleophile (small, high charge density).
$$PhO^-$$ (phenoxide) is a moderate nucleophile (resonance-stabilized, less nucleophilic than OH⁻).
$$CH_3COO^-$$ (acetate) is a weak nucleophile (resonance-stabilized carboxylate).
$$ClO_4^-$$ (perchlorate) is an extremely weak nucleophile (highly stabilized by resonance).
Order of nucleophilicity: $$^-OH > PhO^- > CH_3COO^- > ClO_4^-$$
The answer is Option 2: $$^-OH > PhO^- > CH_3COO^- > ClO_4^-$$.
