Haloalkane is a polar molecule that undergoes nucleophilic substitution through SN1 and SN2. Arrange the following haloalkanes in order of increasing rate of unimolecular nucleophilic substitution reaction:
I. 2-chloro-2-methylpropane
II. 2-chlorobutane
III. 1-chlorobutane
I< II < III
I< III < II
III< I < II
III< II < I
