Question

Buna-N is a co-polymer of 1, 3-butadiene and \[\ce{\underset{-}{X}}\] .What is \[\ce{\underset{-}{X}}\]?

Options

• CH₂ = CH – CN

• CH₂ = CH – CI

• CH₂ = CH – C₆H₅

• CH₂ = CH – CH₃

Answer 1

CH₂ = CH – CN

Explanation:

BUNA - N is a copolymer of 1, 3 - butadiene and acrylonitrile.

\[\ce{\underset{1, 3-butadiene}{nH2C = CH - CH = CH2} + \underset{Acrylonitrile}{nH2C = CH - CN}}\]

                                                 BUNA – N
