   In ${\mathrm{S}}_{\mathrm{N}}2$ reactions, the correct order of reactivity for the following compounds: $\mathrm{C}{\mathrm{H}}_3\mathrm{Cl}$, $\mathrm{C}{\mathrm{H}}_3\mathrm{C}{\mathrm{H}}_2\mathrm{Cl}$, $(\mathrm{C}{\mathrm{H}}_3{)}_2\mathrm{CHCl}$ and $(\mathrm{C}{\mathrm{H}}_3{)}_3\mathrm{CCl}$ is:

   1. A.$\mathrm{C}{\mathrm{H}}_3\mathrm{C}{\mathrm{H}}_2\mathrm{Cl}>\mathrm{C}{\mathrm{H}}_3\mathrm{Cl}>(\mathrm{C}{\mathrm{H}}_3{)}_2\mathrm{CHCl}>(\mathrm{C}{\mathrm{H}}_3{)}_3\mathrm{CCl}$
   2. B.$(\mathrm{C}{\mathrm{H}}_3{)}_2\mathrm{CHCl}>\mathrm{C}{\mathrm{H}}_3\mathrm{C}{\mathrm{H}}_2\mathrm{Cl}>\mathrm{C}{\mathrm{H}}_3\mathrm{Cl}>(\mathrm{C}{\mathrm{H}}_3{)}_3\mathrm{CCl}$
   3. C.$\mathrm{C}{\mathrm{H}}_3\mathrm{Cl}>(\mathrm{C}{\mathrm{H}}_3{)}_2\mathrm{CHCl}>\mathrm{C}{\mathrm{H}}_3\mathrm{C}{\mathrm{H}}_2\mathrm{Cl}>(\mathrm{C}{\mathrm{H}}_3{)}_3\mathrm{CCl}$
   4. D.$\mathrm{C}{\mathrm{H}}_3\mathrm{Cl}>\mathrm{C}{\mathrm{H}}_3\mathrm{C}{\mathrm{H}}_2\mathrm{Cl}>(\mathrm{C}{\mathrm{H}}_3{)}_2\mathrm{CHCl}>(\mathrm{C}{\mathrm{H}}_3{)}_3\mathrm{CCl}$
