Arrange the following halides in order of increasing S_N2 reactivity:
CH₃Cl, CH₃Br, CH₃CH₂Cl, (CH₃)₂CHCl.

Solution

C-Cl bond is stronger and more diffcult to cleave than C-Br bond. Also, as the size of the alkyl group increase, the S_N2 reactivity decrease. Thus order is given by,
(CH₃)₂CHCl < CH₃CH₂Cl < CH₃Cl < CH₃Br.
