Question

Decreasing order of reactivity towards SN² displacement:
1-Bromobutane, 1-Bromo-2, 2-dimethyl propane, 1-Bromo-2-methylbutane,
1-Bromo-3-methylbutane​

Answer 1

Answer:

Thus, the reactivity of the given alkyl bromides decreases in the order: 1-Bromobutane > 1-Bromo-3-methylbutane > 1-Bromo-2-methylbutane > 1-Bromo-2,2-dimethylpropane.
