什么是有机化学?
什么是有机化学?
Organic chemistry is the study of compounds of carbon called organic compounds. Organic compounds either originate from living organisms or are ...
原子的电子结构
原子的电子结构
An atom comprises protons and neutrons, which are contained inside the dense, central core called the nucleus, with electrons present around the ...
电子配置
电子配置
Electron configurations and orbital diagrams can be determined by applying the Aufbau principle (each added electron occupies the subshell of lowest ...
化学键
化学键
Atoms participate in a chemical bond formation to acquire a completed valence-shell electron configuration similar to that of the noble gas nearest ...
极性共价键
极性共价键
Covalent bonds are formed between two atoms when both have similar tendencies to attract electrons to themselves (i.e., when both atoms have identical or ...
Lewis 结构和正式指控
Lewis 结构和正式指控
Lewis symbols can be used to indicate the formation of covalent bonds, which are shown in Lewis structures—drawings that describe the bonding in ...
VSEPR 理论
VSEPR 理论
Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure around a central atom from an examination of the ...
分子几何和偶极矩
分子几何和偶极矩
The VSEPR theory can be used to determine the electron pair geometries and molecular structures as follows: Write the Lewis structure of the molecule or ...
共振和混合结构
共振和混合结构
According to the theory of resonance, if two or more Lewis structures with the same arrangement of atoms can be written for a molecule, ion, or radical, ...
价键理论和杂化轨道
价键理论和杂化轨道
According to valence bond theory, a covalent bond results when: (1) an orbital on one atom overlaps an orbital on a second atom, and (2) the single ...
MO 理论和共价键
MO 理论和共价键
The molecular orbital theory describes the distribution of electrons in molecules in a manner similar to the distribution of electrons in atomic orbitals. ...
分子间作用力和物理性质
分子间作用力和物理性质
Intermolecular forces are attractive forces that exist between molecules. They dictate several bulk properties, such as melting points, boiling points, ...
溶解度
