Molecular geometry — Geometry of the water molecule Molecular geometry or molecular structure is the three dimensional arrangement of the atoms that constitute a molecule. It determines several properties of a substance including its reactivity, polarity, phase of… … Wikipedia
Octahedral molecular geometry — Idealized structure of a compound with octahedral coordination geometry. In chemistry, octahedral molecular geometry describes the shape of compounds where in six atoms or groups of atoms or ligands are symmetrically arranged around a central… … Wikipedia
Bent bond — Bent bond, also known as banana bond, is a term in organic chemistry that refers to a type of covalent chemical bond with a geometry somewhat reminiscent of a banana. The term itself is a general representation of electron density or… … Wikipedia
Molecular orbital diagram — A molecular orbital diagram, or MO diagram for short, is a qualitative descriptive tool explaining chemical bonding in molecules in terms of molecular orbital theory in general and the Linear combination of atomic orbitals molecular orbital… … Wikipedia
Bent bond (disambiguation) — The term bent bond generally refers to any form of bond in a structure that resembles the shape of a banana, but may also refer to:* In VSEPR Theory and molecular geometry, a structure which contains one or two lone pairs. * Rarely, in… … Wikipedia
Quintuple bond — A quintuple bond in chemistry is an unusual type of chemical bond first reported in 2005 for a dichromium compound. Single bonds, double bonds, and triple bonds are commonplace in chemistry. Quadruple bonds are rarer but occur especially for Cr,… … Wikipedia
VSEPR theory — Valence shell electron pair repulsion (VSEPR) theory is a model in chemistry used to predict the shape of individual molecules based upon the extent of electron pair electrostatic repulsion.[1] It is also named Gillespie–Nyholm theory after its… … Wikipedia
Nucleic acid double helix — Double helix redirects here. For other uses, see Double helix (disambiguation). Two complementary regions of nucleic acid molecules will bind and form a double helical structure held together by base pairs. In molecular biology, the term double… … Wikipedia
