A) neoprene
B) chloroprene
C) glyptal
D) nylon
Correct Answer: A
Solution :
Neoprene is the polymer of chloroprene (2-chloro-but 1, 3-diene). It resembles in appearance with natural rubber. \[nC{{H}_{2}}=CH-\underset{\begin{smallmatrix} | \\ Cl \end{smallmatrix}}{\mathop{C}}\,=C{{H}_{2}}\xrightarrow[{}]{polymerisation}\] \[{{\left[ \underset{Neoprene}{\mathop{-C{{H}_{2}}-CH=\underset{\begin{smallmatrix} | \\ Cl \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{2}}-}}\, \right]}_{n}}\]
