Multiple Choice Options

  • A H2C=CH−CH=CH2{H_2}C = CH - CH = C{H_2} and      \,\,\,\,\, H5C6−CH=CH2{H_5}{C_6} - CH = C{H_2}
  • B H2C=CH−CN{H_2}C = CH - CN and      \,\,\,\,\, H2C=CH−CH=CH2{H_2}C = CH - CH = C{H_2}
  • C 0
  • D 0

Step-by-Step Verified Solution

Buna −- NN is a copolymer of butadiene (CH2=CH−CH=CH2)\left( {C{H_2} = CH - CH = C{H_2}} \right) and acrylonitrile (CH2=CHCN).\left( {C{H_2} = CHCN} \right).
