How does the presence of double bonds in rubber molecules influence their structure and reactivity?


Natural rubber is a linear cis-1, 4-polyisoprene in which double bonds are present between C2& C3. It increases the elasticity of the rubber, as the chains are held together by weak van der waals forces and have coiled structure. Therefore, the natural rubber has coiled structure & shows elasticity & is non-crystalline.
