MCQ
Correct order of nucleophilicity
  • A
    $CH_3O^- > CH_3^- > NH_2^- > CH_3COO^-$
  • B
    $CH_3^- > NH_2^- > CH_3O^- > CH_3COO^-$
  • C
    $NH_2^- > CH_3^- > CH_3O^- > CH_3COO^-$
  • D
    $CH_3^- > CH_3O^- > NH_2^- > CH_3COO^-$

Answer

As electronegativity of the central atom decreases, its nucleophilicity increases. Here,  carbon has the least electronegativity. So, $C H_{3}^{-}$ will have the highest nucleophilicity.
