Answer»

Solution :(i) Butadiene , `CH_2=CH-CH=CH_2` , STYRENE, `C_6H_5 -CH=CH_2`
(ii) Butadiene , `CH_2=CH-CH=CH_2` , ACRYLONITRILE , `CH_2=underset(CN)underset(|)CH`
(iii) Terephthalic ACID , , ETHYLENE glycol ( Ethane-1,2- diol) `{:(CH_2OH),(|),(CH_2OH):}`
(iv) Chloroprene , `CH_2= underset(Cl)underset(|)C-CH=CH_2`,2-Chloro-1,3- butadine is the monomerof NEOPRENE .
