Question

For the following the increasing order of nucleophilicity would be: (in protic solvent)
(i) $I^{-}$
(ii) $C{l}^{-}$
(iii) $B{r}^{-}$

• A. $I^{-}<C{l}^{-}<B{r}^{-}$
• B. $B{r}^{-}<C{l}^{-}<I^{-}$
• C. $I^{-}<Br<C{l}^{-}$
• D. $C{l}^{-}<B{r}^{-}<I^{-}$

Answer 1

Answer: (D)

On going top to bottom in group nucleophilicity increases.
