(a)
Interpretation:
The structure of the natural rubber, gutta-percha is to be drawn.
Concept introduction:
Gutt-percha is the polyterpene which formed by the
(b)
Interpretation:
The reason corresponding to the fact that gutta-percha is not vey elastic even after it is vulcanised is to be stated.
Concept introduction:
Gutt-percha is the polyterpene which formed by the polymer of isoprene unit. All the double bonds in this polyterpene are positioned in the trans configuration. Thus, it is also known as
The chemical process of making the rubber more strong and elastic by heating it with sulphur is known as vulcanization of rubber. In this process, a three-dimensional cross-linking of polyisoprene bonded with each other by sulphur atoms takes place.
