WebIn group theory, geometry, representation theory and molecular geometry, a symmetry operation is a geometric transformation of an object that leaves the object looking the same after it has been carried out. For example, as transformations of an object in space, rotations, reflections and inversions are all symmetry operations. Such symmetry … WebSee also [ edit] Piperidine, a cyclic six-membered amine that results from hydrolysis of piperine. Piperic acid, the carboxylic acid also derived from hydrolysis of piperine.

WebDibromomethane is prepared commercially from dichloromethane via bromochloromethane: 6 CH 2 Cl 2 + 3 Br 2 + 2 Al → 6 CH 2 BrCl + 2 AlCl 3 CH 2 Cl 2 + HBr → CH 2 BrCl + HCl. The latter route requires aluminium trichloride as a catalyst. The bromochloromethane product from either reaction can further react in a similar manner: list of eating disorders and definitions
