Chemistry - AMINES Question with Solution | TestHub

$\mathrm{C}{\mathrm{H}}_3\mathrm{C}{\mathrm{H}}_2\mathrm{B}\mathrm{r}$is more reactive in${\mathrm{S}}_{\mathrm{N}}2$reactions. In$(\mathrm{C}{\mathrm{H}}_3{)}_3\mathrm{C}\mathrm{B}\mathrm{r}$, steric hindrance at the carbon of$\mathrm{C}-\mathrm{B}\mathrm{r}$is very high, therefore, the nucleophilic attack of phthalimide anion is mechanically hindered.

The$-\mathrm{C}{\mathrm{H}}_3$and$-\mathrm{O}\mathrm{C}{\mathrm{H}}_3$are electron-donating groups, which do not activate Br atom for nucleophilic substitutions reactions. Hence, compounds C and D are not also used for the preparation of amines.
