WebThe particle model has four main tenets: All substances are made of particles. The particles are attracted to each other (some strongly, others weakly). The particles move around (have kinetic energy). As temperature increases, the particles move more (their kinetic energy increases). A solid particle diagram.

WebRetrosynthetic analysis. Retrosynthetic analysis is a technique for solving problems in the planning of organic syntheses. This is achieved by transforming a target molecule into simpler precursor structures regardless of any potential reactivity/interaction with reagents. Each precursor material is examined using the same method. WebSep 16, 2024 · Most chemical reactions can be classified into one or more of five basic types: acid–base reactions, exchange reactions, condensation reactions (and the reverse, cleavage reactions), and oxidation–reduction reactions. The general forms of these five kinds of reactions are summarized in Table 7.10.1, along with examples of each.
Molecular descriptors play a fundamental role in chemistry, pharmaceutical sciences, environmental protection policy, and health researches, as well as in quality control, being the way molecules, thought of as real bodies, are transformed into numbers, allowing some mathematical treatment of the chemical information contained in the molecule.
