Question

Buna-N synthetic rubber is obtained by the copolymerisation of ______.

Options

• \[\ce{CH2 = CH - CH = CH2 and H5C6 - CH = CH2}\]

• \[\ce{CH2 = CH - CN and H2C = CH - CH = CH2}\]

• \[\ce{H2C = CH - CN and CH2 = CH - C(CH3) = CH2}\]

• \[\ce{H2C = CH - (CCI) = CH2 and H2C = CH - CH = CH2}\]

Answer 1

Buna-N synthetic rubber is obtained by the copolymerisation of \[\underline{\ce{CH2 = CH - CN and H2C = CH - CH = CH2}}\].

Explanation:

Buna-N is obtained by copolymerisation of 1, 3-butadiene and acrylonitrile in the presence of a peroxid catalyst.
