Struttura e legami covalenti

Che cos'è la chimica organica?
Che cos'è la chimica organica?
Organic chemistry is the study of compounds of carbon called organic compounds. Organic compounds either originate from living organisms or are ...
Struttura elettronica degli atomi
Struttura elettronica degli atomi
An atom comprises protons and neutrons, which are contained inside the dense, central core called the nucleus, with electrons present around the ...
Configurazione elettronica
Configurazione elettronica
Electron configurations and orbital diagrams can be determined by applying the Aufbau principle (each added electron occupies the subshell of lowest ...
Legami chimici
Legami chimici
Atoms participate in a chemical bond formation to acquire a completed valence-shell electron configuration similar to that of the noble gas nearest ...
Legami covalenti polari
Legami covalenti polari
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 ...
Strutture di Lewis e carica formale
Strutture di Lewis e carica formale
Lewis symbols can be used to indicate the formation of covalent bonds, which are shown in Lewis structures—drawings that describe the bonding in ...
Teoria VSEPR
Teoria VSEPR
Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure around a central atom from an examination of the ...
Geometria molecolare e momento di dipolo
Geometria molecolare e momento di dipolo
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 ...
Risonanza e strutture ibride
Risonanza e strutture ibride
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, ...
Teoria dei legami di valenza e orbitali ibridi
Teoria dei legami di valenza e orbitali ibridi
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 ...
La teoria degli orbitali molecolari e legame covalente
La teoria degli orbitali molecolari e legame covalente
The molecular orbital theory describes the distribution of electrons in molecules in a manner similar to the distribution of electrons in atomic orbitals. ...
Legami intermolecolari e proprietà fisiche
Legami intermolecolari e proprietà fisiche
Intermolecular forces are attractive forces that exist between molecules. They dictate several bulk properties, such as melting points, boiling points, ...
Solubilità
Solubilità
Solution, Solubility, and Solubility Equilibrium A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the ...
Introduzione ai gruppi funzionali
Introduzione ai gruppi funzionali
Functional groups are group of atoms with specific chemical properties that occur within organic molecules and sometimes denoted as “R”. ...
