Chemistry Question on Organic Chemistry- Some Basic Principles and Techniques

Nucleophilicity order is correctly represented by

A

NH2−>F−>OH−>CH3−NH^-_2 > F^- > OH^- > CH^-_3

B

CH3−>NH2−>OH−>F−CH^-_3 > NH^-_2 > OH^- > F^-

C

CH2−>OH−>F−>NH2−CH^-_2 > OH^- > F^- > NH^-_2

D

NH2−>F−>CH3−>OH−NH^-_2 > F^- > CH_3^- > OH^-

Answer

CH3−>NH2−>OH−>F−CH^-_3 > NH^-_2 > OH^- > F^-

Explanation

Solution

Within a period, nucleophilicity follows the order of basicity. Lesser the electronegativity of the donor atom, more is its tendency to give a lone pair of electrons, more is its nucleophilicity. Thus, the order of nucleophilicity is CH3−>NH2−>OH−>F−CH^{-}_{3} > NH^{-}_{2} > OH^{-} > F^{-}.
