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 ...
tert-Butylbenzene is an organic compound classified as an aromatic hydrocarbon. Its structure consists of a benzene ring substituted with a tert -butyl group . It is a flammable colorless liquid which is nearly insoluble in water but miscible with organic solvents.
The chemical chameleon reaction shows the process in reverse, by reducing violet potassium permanganate first to green potassium manganate and eventually to brown manganese dioxide: [1] [2] [5] KMnO 4 (violet) → K 2 MnO 4 (green) → MnO 2 (brown/yellow suspension) Blue potassium hypomanganate may also form as an intermediate.

Cation–π interaction between benzene and a sodium cation.. Cation–π interaction is a noncovalent molecular interaction between the face of an electron-rich π system (e.g. benzene, ethylene, acetylene) and an adjacent cation (e.g. Li +, Na +).
Crystalline potassium permanganate (KMnO 4) is placed in an evaporating dish. A depression is made at the center of the permanganate powder and glycerol liquid is added to it. The white smoke-like vapor produced by the reaction is a mixture of carbon dioxide gas and water vapor.
There are still more than 40 days until Trump takes office, and Justice Department prosecutors continue to press cases against individual rioters, but the coming administration change hasn’t ...
Harvard tied with Dartmouth and Columbia atop the conference at 5-2 this season, but scored head-to-head wins over both teams. Officially, the Ivy League recognized all three teams as co-champions.
