Q88 / 180 · NEET 2016 (Phase 1) · Chemistry

Natural rubber has:

  • Correct answer
    A
    All cis - configuration
  • B
    All trans - configuration
  • C
    Alternate cis - and trans - configuration
  • D
    Random cis - and trans - configuration

Solution

The natural rubber has an isoprene monomer unit. All isoprene units are present as the cis-configuration.

When isoprene units are combined together in cis configuration then natural rubber is formed.

The structure for the same is given below:

Figure

Hence, the correct answer is option: 'A'.
