Question
Wired Faculty App

In the following pairs of halogen compounds, which compound undergoes faster SN1 reaction?

         and        

 

Answer

Greater the stability of the carbocation, faster is the rate of SN1 reaction. Since tertiary carbocation 2-chloro-2-methylpropane is more stable than secondary carbocation 3-chloropentane. Hence SN1 reaction proceed via tertiary cation such as 2-chloro-2-methylpropane.
