Vedclass · Answer

(A) Natural rubber is a polymer of isoprene ($2$-methyl-$1,3$-butadiene). Its structure is $(CH_2-C(CH_3)=CH-CH_2)_n$. On complete hydrogenation,the double bonds in the polymer chain are saturated with hydrogen atoms. The resulting structure is $(CH_2-CH(CH_3)-CH_2-CH_2)_n$,which is identical to the structure of an ethylene-propylene copolymer.
