Chemistry - Halogen Derivative Question with Solution | TestHub

Alkyl halide gives alkene on elimination, reaction takes place in presence of alc.$\mathrm{K}\mathrm{O}\mathrm{H}$.
$\mathrm{C}{\mathrm{H}}_3\mathrm{C}{\mathrm{H}}_2\mathrm{B}\mathrm{r}+\mathrm{A}\mathrm{l}\mathrm{c}\mathrm{}\mathrm{}.\mathrm{}\mathrm{}\mathrm{K}\mathrm{O}\mathrm{H}\to \mathrm{C}{\mathrm{H}}_2=\mathrm{C}{\mathrm{H}}_2+\mathrm{K}\mathrm{B}\mathrm{r}+{\mathrm{H}}_2\mathrm{O}$
There are two types of elimination reactions.
(A)${\mathrm{E}}_1\to$Unimolecular elimination
(B)${\mathrm{E}}_2\to$Bimolecular elimination
