Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are possibly arranged in the real three-dimensional space.
In chemical graph theory and in mathematical chemistry, a molecular graph or chemical graph is a representation of the structural formula of a chemical compound in terms of graph theory. A chemical graph is a labeled graph whose vertices correspond to the atoms of the compound and edges correspond to chemical bonds.
E)-Stilbene, commonly known as trans-stilbene, is an organic compound represented by the condensed structural formula C 6 H 5 CH=CHC 6 H 5. Classified as a diarylethene , it features a central ethylene moiety with one phenyl group substituent on each end of the carbon–carbon double bond .
For example, the compound dichlorine hexoxide has an empirical formula ClO 3, and molecular formula Cl 2 O 6, but in liquid or solid forms, this compound is more correctly shown by an ionic condensed formula [ClO 2] + [ClO 4] −, which illustrates that this compound consists of [ClO 2] + ions and [ClO 4] − ions. In such cases, the condensed ...
Triphenylethanol, or 1,1,2-triphenylethanol, is an organic compound with a condensed structural formula of (C 6 H 5) 2 C(OH)CH 2 C 6 H 5, and is related to triphenylethylene, from which it can be prepared by hydration.
A general formula for such cyclic compounds is [HPO 3] x where x = number of phosphoric units in the molecule. When metaphosphoric acids lose their hydrogens as H +, cyclic anions called metaphosphates are formed. An example of a compound with such an anion is sodium hexametaphosphate (Na 6 P 6 O 18), used as a sequestrant and a food additive.
These can be described by the condensed structural formulas and (). The third isomer of C 3 H 8 O {\displaystyle {\ce {C3H8O}}} is the ether methoxyethane (ethyl-methyl-ether; III ). Unlike the other two, it has the oxygen atom connected to two carbons, and all eight hydrogens bonded directly to carbons.
In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, derived from either of the two isomers (n-butane and isobutane) of butane. The isomer n -butane can connect in two ways, giving rise to two "-butyl" groups:
