Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3 (in which the bond angle between the nitrogen and hydrogen is 170°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...
The amino radical has two characteristic electronic states: The more stable electronic state is 2 B 1, where the unpaired electron is in the p-orbital perpendicular to the plane of the molecule (π type radical). The high energy electronic state, 2 A 1, has the two electrons in the p-orbital and the unpaired electron in the sp 2 orbital (σ ...
NH2 or similar may refer to: Azanide (chemical formula NH − 2) Amino radical (chemical formula NH • 2) Nitrenium ion (chemical formula NH + 2) Primary amide group (chemical formula -NH 2) National Harbor–Alexandria Line (Route NH2), a WMATA bus line between Alexandria, Virginia and Prince George's County, Maryland; National Highway 2 (India)
A carbon–nitrogen bond is a covalent bond between carbon and nitrogen and is one of the most abundant bonds in organic chemistry and biochemistry. [1]Nitrogen has five valence electrons and in simple amines it is trivalent, with the two remaining electrons forming a lone pair.
Electrostatic potential map of a water molecule, where the oxygen atom has a more negative charge (red) than the positive (blue) hydrogen atoms. Electronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons (or electron density) when forming a chemical bond. [1]
Old Lyme class action lawsuit, it claims Old Lyme Gourmet Co. labeled certain Deep River brand chips with the “non-GMO ingredients” graphic, giving consumers the impression the snacks were ...
These IVAP defects consist of a dangling bond containing two electrons (D −) and a dangling bond containing no electrons (D +). When one of these pairs is illuminated, it can capture an electron or an electron hole resulting in the following reactions: [1] D + D − + e − → D 0 D −. D + D − + h + → D + D 0. Here, D 0 is an uncharged ...
