Question

The correct order of nucleophilicity is

• A. $F^{-}>O{H}^{-}$
• B. $H_{2}O>O{H}^{-}$
• C. $ROH>R{O}^{-}$
• D. $N{H}_2^{-}>N{H}_3$

Answer 1

Answer: (D)

Nucleophilicity $\propto$ electro density on donor atom
$\propto$ size of donor atom (in gas)
$\propto \frac{1}{\text{ EN of atom }}$ (for period)
