A) vinyl cyanide
B) acrolein
C) glycol
D) isoprene
Correct Answer: A
Solution :
Orlon is a polymer of acrylonitrile or vinyl cyanide. It is the example of polyacrylate \[n{{H}_{2}}C=\underset{\begin{align} & CN \\ & Vinyl\,cyanide \\ & or \\ & acrylo\,nitrile \\ \end{align}}{\mathop{\underset{|}{\mathop{C}}\,}}\,H\xrightarrow{peroxide}\] \[\underset{\begin{smallmatrix} polyacrylo\,nitrite\,(PAN) \\ or\,orlon\,or\,Acilan \end{smallmatrix}}{\mathop{{{\left[ -C{{H}_{2}}-\underset{CN}{\mathop{\underset{|}{\mathop{C}}\,}}\,H- \right]}_{n}}}}\,\] Orion is hard horny and has high melting point. It is used in preparing cloth, carpets and blanket. Isoprene is the monomer of natural rubber \[{{H}_{2}}C=\underset{\begin{smallmatrix} C{{H}_{3}} \\ Isoprene \end{smallmatrix}}{\mathop{\underset{|}{\mathop{C}}\,}}\,HC=C{{H}_{2}}\] \[\xrightarrow{{}}\,\,[-C{{H}_{2}}-\underset{\begin{smallmatrix} C{{H}_{3}} \\ Natural\, \end{smallmatrix}}{\mathop{\underset{|}{\mathop{C}}\,}}\,=CH-C{{H}_{2}}-]\]
