NEET levelSingle correct optionDifficulty 1 of 3pl074

The monomer of natural rubber is

Achloroprene (2-chlorobuta-1,3-diene)
Bisoprene (2-methylbuta-1,3-diene)
Cbuta-1,3-diene
Dstyrene

Answer: B

Natural rubber is cis-1,4-polyisoprene, built from 2-methylbuta-1,3-diene,

CH X_{2} = C (CH X_{3}) - CH = CH X_{2}
