Gold Nanoparticles, Amine Functional(氨基修饰纳米金) These include its electronegativity, its molecular geometry and its resulting dipole moment, if any.【改性的表面活性基团纳米金Gold Nanoparticles Functional】: To determine the polarity of the NH 2 – ion, we must first account for its properties. A schematic equation of this reaction is shown below:Ģ M + 2 NH 3 → 2 MNH 2 + H 2 (M = Li, Na, K) This leads to the formation of the Azanide anion.Īlkali metal derivatives (also known as alkali metal amides) such as Sodium Amide, Lithium Amide and Potassium Amide, are produced when liquid Ammonia is treated with strong bases. The following tables list common functional groups arranged by heteroatom. Deprotonation of Ammonia occurs when it reacts with strong bases or alkali metals. Functional groups A Last updated Molecular Classes Homolytic C-H Bond Dissociation Energies of Organic Molecules In organic chemistry, functional groups are specific groups of atoms within molecules arranged in a specific manner. Unlike its organic counterpart, the Azanide ion is a conjugate base of Ammonia. Classify an organic molecule according to the functional group (s) that it contains. The term ‘amide’ also refers to the –C(O)NR 2, which is an organic functional group. Define the following terms: functional group, alkene, alkyne, aromatic, halide, alcohol, ether, thiol, sulfide, amine, carbonyl, aldehyde, ketone, carboxylic acid, ester, amide. The derivatives of the NH 2 – ion are referred to as amides. Azanide is the IUPAC name of the ion, however this nomenclature is obscure. The chemical formula NH 2 – represents the Azanide ion. ![]()
