Buna-N synthetic rubber is a copolymer of:

Answer»

`H_2C=CH-CH=CH_2` and `H_5C_6-CH=CH_2`
`H_2C=CH-CN` and `H_2C=CH-CH=CH_2`
`H_2C=CH-CN` and `H_2C=CH-underset(CH_3)underset(|)C=CH_2`
`H_2C=CH-overset(Cl)overset|C=CH_2` and `H_2C=CH-CH=CH_2`

SOLUTION :Buna-N is a COPOLYMER of butadiene `(CH_2=CH-CH=CH_2)` and ACRYLONITRILE `(CH_2=CHCN)`.
