Write the name and the structure of the monomer of natural rubber polymers.

The monomer of natural rubber is isoprene.

Name:
2-Methyl-1,3-butadiene (commonly known as isoprene).

Structure:
The structure of isoprene is:

CH₂=C(CH₃)-CH=CH₂

Explanation:
Isoprene is a diene, meaning it has two double bonds.
The polymerization of isoprene units through a 1,4-addition reaction forms natural rubber (polyisoprene).
In this polymerization, the double bonds of the isoprene units react, resulting in a long chain polymer. The structure of polyisoprene consists of repeating units of isoprene monomers.
