Step by step solution

01

Isoprene

The organic compound that has five carbons in the hydrocarbon skeleton with two double bonds is isoprene. This compound makes very basic structural units for rubbers.

02

Isoprene units

The main rule to identify an isoprene unit is that it should contain five carbon atoms. The isoprene unit is made up of two parts: one is the head and another one is the tail; the head is at the branched end and the tail is at the un-branched end.
