The simplest amino acid is glycine, H2NCH2CO2H. The common feature of amino acids is that they contain the functional groups: an amine group, –NH2, and a carboxylic acid group, –CO2H. An amino acid can function as either an acid or a base. For glycine, the acid strength of the ca...

第二章Lewis结构与共振论
H2NNH2, hydrazine (Hint: Draw the Lewis dot structure.) Draw electron arrows for the collapse of tetrahedral intermediate and then draw product with all lone pairs. Thanks Write a Lewis structure for NI_3. Show all bonding valence electron pairs ...
Electrons are shared when electrons of one element can satisfy the octet of other elements' atoms. In such cases, atoms share electrons and form covalent bonds, satisfying the octet count for the constituent atoms. Electrons are sometimes given or taken ...
Tungsten nitride films were deposited on heated substrates by the reaction of vapors of tungsten bis(alkylimide)bis(dialkylamide) and a Lewis base or a hydrogen plasma. For example, vapors of tungsten bis(tert-butylimide)bis(dimethylamide) and ammonia gas supplied in alternate doses to surfaces...

Density functional theory (DFT) calculations further support the stability of a dangling Ti-NH2 (amide) structure with an adjacent nitrogen vacancy (Fig. 4b). The charge population analysis reveals that the N3- in Ti-NH2 (N1) acts as a Lewis base with a local atomic charge of -0.81 e, ...
Aluminum hydroxide dissolves in a solution of sodium hydroxide or another strong base because of the formation of the complex ionAl(OH)4-Al(OH)4-. The Lewis structure of theAl(OH)4-Al(OH)4-ion is: The equations for the dissolution are: ...
