A) butadiene and isoprene
B) butadiene and acrylonitrile
C) isoprene and ethylene diamine
D) isoprene and butyl diamine
Correct Answer: B
Solution :
Buna-N is synthetic rubber which is polymer of butadiene with acrylonitrite. \[\underset{1,3-\text{butadiene}}{\mathop{n\,C{{H}_{2}}=CH-CH=C{{H}_{2}}}}\,\] \[\underset{\downarrow }{\mathop{+\,n\,C{{H}_{2}}=CH-CN}}\,\] \[\underset{\text{buna}\,\text{-N}}{\mathop{\left[ -C{{H}_{2}}-CH=CH-C{{H}_{2}}-C{{H}_{2}}-\underset{CN}{\mathop{\underset{|}{\mathop{CH}}\,}}\,- \right]}}\,\]
