Alkene carboamination is the simultaneous formation of C–N and C–C bonds across an alkene.This method represents a powerful strategy to build molecular complexity with up to two stereocenters in a single operation.
In modern chemistry, a chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using a single line of chemical element symbols, numbers, and sometimes other symbols, such as parentheses, brackets, and plus (+) and minus (−) signs.

In solution chemistry and biochemistry, the Gibbs free energy decrease (∂G/∂ξ, in molar units, denoted cryptically by ΔG) is commonly used as a surrogate for (−T times) the global entropy produced by spontaneous chemical reactions in situations where no work is being done; or at least no "useful" work; i.e., other than perhaps ± P dV.
A concise four-page summary of the most important material in the Green Book was published in the July–August 2011 issue of Chemistry International, the IUPAC news magazine. The second edition of the Green Book (ISBN 0-632-03583-8) was first published in 1993. It was reprinted in 1995, 1996, and 1998.
Well characterized examples of transition metal peroxides include the d 10 metal cations: zinc peroxide (ZnO 2), two polymorphs (both explosive) of mercury peroxide (HgO 2), and cadmium peroxide (CdO 2). Peroxide is a common ligand in metal complexes. Within the area of transition metal dioxygen complexes, O 2− 2 functions as a bidentate ...
All India Secondary School Examination, commonly known as the class 10th board exam, is a centralized public examination that students in schools affiliated with the Central Board of Secondary Education, primarily in India but also in other Indian-patterned schools affiliated to the CBSE across the world, taken at the end of class 10.
