Rubber and gutta-percha molecular models
Molecular models of rubber and gutta-percha. These molecules are isomers. They have the same chemical fourmula but a different molecular structure. In this example, gutta-percha is the trans isomer (the side-chains alternate) and rubber is the cis isomer (the side-chains are on the same side). Gutta-percha is obtained from the Isonandra gutta tree, while rubber is obtained from the Hevea braziliensis tree. The difference in molecular structure means that gutta-percha has a higher melting point than rubber

EDITORS COMMENTS
This print showcases molecular models of rubber and gutta-percha, two fascinating isomers with the same chemical formula but different molecular structures. In this particular example, gutta-percha represents the trans isomer, characterized by alternating side-chains, while rubber embodies the cis isomer with side-chains on the same side. Derived from distinct trees - Isonandra gutta for gutta-percha and Hevea braziliensis for rubber - these polymers possess contrasting melting points due to their dissimilar molecular structures. Gutta-percha exhibits a higher melting point compared to rubber. The image beautifully captures the intricate bond between atoms in both molecules, emphasizing their structural differences. The horizontal arrangement of chains and bonds provides an educational insight into polymer chemistry. Each atom and hydrogen pair plays a crucial role in forming these long-chain carbon structures. This photograph not only serves as a valuable resource for scientific education but also highlights nature's contribution to our understanding of materials like rubber and gutta-percha. It reminds us that even seemingly ordinary objects have complex molecular compositions that shape their properties. Courtesy of Science Photo Library, this visually stunning print invites viewers to delve into the world of organic chemistry and appreciate how small variations in molecular structure can lead to significant differences in material characteristics.
