WebFor example, many (but not all) covalent bonds allow the groups of atoms they connect to freely rotate around the axis of the bond. This lets the molecule take on many different conformations. Figure 4-7 shows a very popular molecule: sucrose, also known as table sugar. It is shown both as a 2D chemical structure and as a 3D conformation. WebTopological indexes should be based on the most significant features of molecular structure, including atom identity, bonding environment of each atom, and the existence of hydrogen atoms bonded to the skeletal atom. Each of these aspects is distinctly electronic in nature. [Pg.371] The major concern is that of skin sensitisation.

WebThe structure of DNA, as represented in Watson and Crick's model, is a double-stranded, antiparallel, right-handed helix. The sugar-phosphate backbones of the DNA strands make up the outside of the helix, while the nitrogenous bases are found on the inside and form hydrogen-bonded pairs that hold the DNA strands together. WebThe cross-linked molecular structure is a key feature of thermosetting polymers. The cross-linked structure is created in a variety of ways for thermosetting. Polymer is produced by combining two or more chemicals in the thermosetting process. These compounds form a thermosetting polymer by cross-linking with one another.

WebPolypropylene (PP) is a tough, rigid, and crystalline thermoplastic. It is made from propene (or propylene) monomer.
