1-chloro-2-methylpropane and 2-bromo-2-methylbutane are each reacted separately with aqueous silver nitrate in ethanol. In both cases, nucleophilic substitution occurs and a precipitate is produced. The time needed for 1-chloro-2-methylpropane to produce a precipitate is $T_1$. The time needed for 2-bromo-2-methylbutane to produce a precipitate is $T_2$. Which row is correct?
- A1-chloro-2-methylpropane; main reaction mechanism $S_N1$; time taken for precipitate to appear $T_2 > T_1$
- B1-chloro-2-methylpropane; main reaction mechanism $S_N2$; time taken for precipitate to appear $T_1 > T_2$
- C2-bromo-2-methylbutane; main reaction mechanism $S_N1$; time taken for precipitate to appear $T_2 > T_1$
- D2-bromo-2-methylbutane; main reaction mechanism $S_N2$; time taken for precipitate to appear $T_1 > T_2$
