ChemistrySingle correct+4 / -1Question 71 of 90

The correct order of nucleophilicity is

\mathrm{F^->OH^-}

\mathrm{H_2\ddot O>OH^-}

\mathrm{R\ddot OH>RO^-}

\mathrm{NH_2^->NH_3}

Answer and worked solution

Official answer: D

Nucleophilicity. An anion is a stronger nucleophile than its conjugate acid: $\mathrm{NH_2^->NH_3}$ . The others are reversed ( $\mathrm{OH^->F^-}$ in water, $\mathrm{OH^->H_2O}$ , $\mathrm{RO^->ROH}$ ).
