Chemical Diagram Maker

Chemistry studies and analyses the structure, properties, and behavior of various elements and compounds, and their changes as a result of chemical reactions with releasing or absorbing energy. This science actively uses structure diagrams to represent visually the compounds' structure, explain their properties and features, chemical patterns, logic combinations, the nature of the functional groups. It is especially actual for organic chemistry involving large molecules and complex compounds. They help to show and understand the structure of chemical bonds. Many chemical compounds exist in different isomeric forms, they have the same molecular formula while their enantiomeric structures differ. The Kekule formulas, Condensed formulas, Skeletal structures, Lewis Structures, Haworth projections, Newman projections, and Fischer projections are used in organic chemistry to depict the structural formulas of chemical compounds.

Kekule formulas are structural formulas displaying how the atoms are bonded in the molecules by covalent bonds. The bonds are shown by the lines; a single line corresponds to a single covalent bond, a double line to a double bond, etc.

Lewis structures are flat graphical formulas mostly used for small molecules. They give an overview of the molecular and electronic geometry of the molecules, show the connections between atoms and lone paired or unpaired electrons. The bonds are often drawn at certain angles. Lewis structures determine the bond angles and hybridization. A single bond of two electrons is shown by a single line, double and triple bonds are shown by two and three parallel lines between pairs of atoms. Pairs of dots show the bonding pairs, all non-bonded electrons both paired and unpaired are also indicated.

Skeletal formulas are used for complex organic molecules. The carbon atoms are located at the vertices and ends of line segments, a positive or negative charge at a carbon atom is indicated. The hydrogen atoms attached to carbon atoms and forming four bonds are not indicated in the schematic, while ones attached to atoms of other elements are indicated. The three-dimensional structure is illustrated using skeletal formulas.

The structural formula is a graphic representation of the molecular structure of a chemical compound in three-dimensional space. All chemical bonding within the molecule is shown. These formulas provide a complete geometric representation of the molecular structure, describe chemical reactions and structural changes that occur during them.
