Solution
The correct option is A True
The given statement is true.
The presence of double bonds in rubber molecules influence their structure and reactivity.
In natural rubber, double bonds have cis configuration. Hence, the chains do not come closer this results in weak intermolecular attractions. Natural rubber has coiled structure, it is elastic and non-crystalline.
In gutta-percha(synthetic rubber) double bonds have trans configuration. The zig-zag chains pack more closely. It is highly crystalline, non elastic, hard & brittle.
