AIEEE 2010 Chemistry - Haloalkanes and Haloarenes Question 142 English Explanation

Since SN1{S_N}1 reactions involve the formation of carbocation as intermediate in the rate determining step, more is the stability of carbocation higher will be reactivity of alkyl halides towards SN1{S_N}1 route. Now we know that stability of carbocations follows the order : {3^ \circ } > {2^ \circ } > {1^ \circ },\,\,\, SN1{S_N}1 reactivity should also follow the same order. {3^ \circ } > {2^ \circ } > 1 > Methyl ( SN1{{S_N}1} reactivity)
