Of two isomers of butylbenzene, n-butylbenzene consists of a phenyl group attached to the 1 position of a butyl group. It is a slightly greasy, colorless liquid. The synthesis of n-butylbenzene by the reaction of chlorobenzene and butylmagnesium bromide was one of the first demonstrations of the Kumada coupling using nickel diphosphine ...
In geology and materials science, a deformation mechanism is a process occurring at a microscopic scale that is responsible for deformation: changes in a material's internal structure, shape and volume. [1] [2] The process involves planar discontinuity and/or displacement of atoms from their original position within a crystal lattice structure.
N-tert-Butylbenzenesulfinimidoyl chloride reacts with enolates, amides, and primary alkoxides by the same general mechanism. The Swern oxidation , which converts primary and secondary alcohols to aldehydes and ketones, respectively, also uses a sulfur-containing compound ( DMSO ) as the oxidant and proceeds by a similar mechanism.
Benzonitrile is a useful solvent and a versatile precursor to many derivatives. It reacts with amines to afford N-substituted benzamides after hydrolysis. [3] It is a precursor to diphenylmethanimine via reaction with phenylmagnesium bromide followed by methanolysis.
To put this in perspective: the lowest excitation vibrational energy in water is the bending mode (about 1600 cm −1). Thus, at room temperature less than 0.07 percent of all the molecules of a given amount of water will vibrate faster than at absolute zero. As stated above, rotation hardly influences the molecular geometry.
Contributing structures of the carbonate ion. In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, [1] also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.

With increasing cluster size the oxygen to oxygen distance is found to decrease which is attributed to so-called cooperative many-body interactions: due to a change in charge distribution the H-acceptor molecule becomes a better H-donor molecule with each expansion of the water assembly. Many isomeric forms seem to exist for the hexamer (H 2 O ...
