2,4,6-Tribromoaniline is a brominated derivative of aniline with the formula C 6 H 4 Br 3 N. It is used in organic synthesis of pharmaceuticals, agrochemicals and fire-extinguishing agents. It is used in organic synthesis of pharmaceuticals, agrochemicals and fire-extinguishing agents.
Anthropogenic and natural sources of bromine. The major sources include sea spray, salt lakes, marshes, volcanos, anthropogenic sources. Sinks include exchange of brominated compounds with the stratospheric and troposphere.Bromine's chemistry is linked to other halogens such as chlorine and iodine amplify atmospheric cycling that contributes to troposphere and stratosphere ozone layer ...
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
For example, aniline has resonance structures with negative charges around the ring system: The amino group can donate electron density through resonance. Attack occurs at ortho and para positions, because the (partial) formal negative charges at these positions indicate a local electron excess.
A phase diagram in physical chemistry, engineering, mineralogy, and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct phases (such as solid, liquid or gaseous states) occur and coexist at equilibrium.
Pourbaix diagram of iron. [1] The Y axis corresponds to voltage potential. In electrochemistry, and more generally in solution chemistry, a Pourbaix diagram, also known as a potential/pH diagram, E H –pH diagram or a pE/pH diagram, is a plot of possible thermodynamically stable phases (i.e., at chemical equilibrium) of an aqueous electrochemical system.
Minerals cycle through the biosphere between the biotic and abiotic components and from one organism to another. [4] Ecological systems have many biogeochemical cycles operating as a part of the system, for example, the water cycle, the carbon cycle, the nitrogen cycle, etc. All chemical elements occurring in organisms are part of ...
The Born–Haber cycle is an approach to analyze reaction energies. It was named after two German scientists, Max Born and Fritz Haber , who developed it in 1919. [ 1 ] [ 2 ] [ 3 ] It was also independently formulated by Kasimir Fajans [ 4 ] and published concurrently in the same journal. [ 1 ]
