Orbital Hybridization
Orbital Hybridization Orbital hybridization controls the local geometry around an atom. More than any other factor, the hybridization state of electron orbitals is responsible for the shape of molecules. Solitary atoms undergo orbital hybridization under the influence of interactions with other atoms. This allows orbitals with different energies…
Molecular Shape
Molecular Shape Important The structure of a molecule is not complete until you know the molecular shape. Molecules which have seemingly an identical molecular shape often have very different chemical properties. The featured image above shows a flow chart you can use to deduce the electron geometry…
Polar Molecule and Nonpolar Molecule
The difference between a polar molecule and a nonpolar molecule depends on molecular geometry. Polar Bonds Polar result when two different elements share electrons and form a covalent bond. Each element has a characteristic electronegativity. A more electronegative element has a stronger attraction for electrons it shares in a…
Electronegativity and Polarity
Bond polarity comes from different elements having different electronegativity; the innate ability to attract electrons within a covalent bond. Electronegativity Each element has a value for electronegativity to compare how two atoms distribute negative charge when they share electrons. Electronegativity Property of Atoms Electronegativity expresses…
Organic Chemistry: 4 Stepping Stones
The four stepping stones to organic chemistry come from general chemistry you already know. Atoms Each element passes important properties through all levels of organization: electronegativity The positive charge from the nucleus compared to the distance of the outer electron gives a different ability to attract…
