Symmetrical mechanism
WebThis method is used to make sterically hindered symmetrical ethers. The mechanism of the sulfuric acid process involves the following five steps. 1. Sulfuric acid dissociates, giving a proton plus the bisulfate ion. 2. The alcohol's oxygen atom is protonated via an acid‐base reaction, leading to the formation of an oxonium ion. 3. WebIn (b), white nodes have moved up, and black nodes down, in the transition from (a). Symmetry shows the existance of a mechanism allowing the transition between the two phases. Compound of ten tetrahedra If considered as pin-jointed, this 'polyhedron' has two classes of mechanism, both of which can be detected using symmetry. Relevant …
