A) I>II>III
B) III>II>I
C) II>I>III
D) I>III>II
Correct Answer: B
Solution :
For\[{{S}_{N}}1\]reactions, greater the stability of carbocations faster will be the rate of reaction. Due to greater stabilisation of benzylic carbocation intermediate by resonance, it shows higher reactivity in\[{{S}_{N}}1\]reactions than other aliphatic halides. Since, the order of reactivity of halides -is benzyl chloride > iso-propyl chloride > ethyl chloride.You need to login to perform this action.
