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 connected to one another. [1] The chemical bonding within the molecule is also shown, either explicitly or implicitly. Unlike other chemical formula types, [a] which have a ...
A space-filling model of n-octane, the straight chain (normal) hydrocarbon composed of 8 carbons and 18 hydrogens, formulae: CH 3 CH 2 (CH 2) 4 CH 2 CH 3 or C 8 H 18.Note, the representative shown is of a single conformational "pose" of a population of molecules, which, because of low Gibbs energy barriers to rotation about its carbon-carbon bonds (giving the carbon "chain" great flexibility ...
Structural chemistry is a part of chemistry and deals with spatial structures of molecules (in the gaseous, liquid or solid state) and solids (with extended structures that cannot be subdivided into molecules). For structure elucidation [1] a range of different methods is used.

[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.
1-Pentyne is an organic compound with the formula CH 3 CH 2 CH 2 C≡CH. It is a terminal alkyne , in fact the smallest that is liquid at room temperature. The compound is a common terminal alkyne substrate in diverse studies of catalysis.
In organic chemistry, an acetyl group is a functional group denoted by the chemical formula −COCH 3 and the structure −C(=O)−CH 3. It is sometimes represented by the symbol Ac [5] [6] (not to be confused with the element actinium). In IUPAC nomenclature, an acetyl group is called an ethanoyl group.
In organic chemistry, an ethyl group (abbr. Et) is an alkyl substituent with the formula −CH 2 CH 3, derived from ethane (C 2 H 6). Ethyl is used in the International Union of Pure and Applied Chemistry 's nomenclature of organic chemistry for a saturated two-carbon moiety in a molecule, while the prefix " eth- " is used to indicate the ...
