This question is about bromoalkanes with the molecular formula $\mathrm{C}_{4} \mathrm{H}_{9} \mathrm{Br}$ .

Give the structure of the $\mathrm{C}_{4} \mathrm{H}_{9} \mathrm{Br}$ bromoalkane that would react fastest with aqueous silver nitrate in ethanol.

The fastest reacting bromoalkane is the tertiary bromoalkane with structure $\ce{(CH3)3CBr}$ , i.e. 2-bromo-2-methylpropane.
