Question

Which of the following is the monomer of neoprene?

Options

• $$\mathrm{CH}{\phantom{A}}_2=\mathrm{CH}-\mathrm{C}\equiv \mathrm{CH}$$

• $$\begin{array}{c}\mathrm{CH}{\phantom{A}}_2=\mathrm{C}-\mathrm{CH}=\mathrm{CH}{\phantom{A}}_2\\ |\phantom{.......}\\ \mathrm{CH}{\phantom{A}}_3\phantom{....}\end{array}$$

• $$\begin{array}{c}\mathrm{CH}{\phantom{A}}_2=\mathrm{C}-\mathrm{CH}=\mathrm{CH}{\phantom{A}}_2\\ |\phantom{.......}\\ \mathrm{Cl}\phantom{......}\end{array}$$

• $$\mathrm{CH}{\phantom{A}}_2=\mathrm{CH}-\mathrm{CH}=\mathrm{CH}{\phantom{A}}_2$$

Answer 1

$$\begin{array}{c}\mathrm{CH}{\phantom{A}}_2=\mathrm{C}-\mathrm{CH}=\mathrm{CH}{\phantom{A}}_2\\ |\phantom{.......}\\ \mathrm{Cl}\phantom{......}\end{array}$$
