10.16 Arrange the compounds of each set in order of reactivity towards SN2 displacement:
(iii) 1-Bromobutane, 1-Bromo-2,2-dimethylpropane, 1-Bromo-2-methylbutane, 1-Bromo-3-methylbutane.
(iii) The steric hindrance is the deciding factor here.
The order of steric hindrance is :-
1-Bromobutane < 1-Bromo-3-methylbutane < 1-Bromo-2-methylbutane< 1-Bromo-2, 2-dimethylpropane
Thus the order of the rate of reaction will be : -
1-Bromo-2, 2-dimethylpropane < 1-Bromo-2-methylbutane < 1-Bromo-3- methylbutane < 1-Bromobutane
