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