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. \[nC{{H}_{2}}=CH-\underset{Cl}{\mathop{\underset{\mathbf{|}}{\mathop{C}}\,}}\,=C{{H}_{2}}\xrightarrow{\text{polymerisation}}\] \[{{\left[ \underset{\text{neoprene}}{\mathop{-C{{H}_{2}}-CH=\underset{Cl}{\mathop{\underset{\mathbf{|}}{\mathop{C}}\,}}\,-C{{H}_{2}}-}}\, \right]}_{n}}\]
