For help on the process, see Wikipedia:How to draw a diagram with Inkscape. This tutorial aims to instruct a beginner on the basic principles of vector graphics using Microsoft Word (Office 97 or later). The basic principles are the same in other drawing programs such as CorelDraw or the free and open source OpenOffice.org.
If SVG files are required, it is recommended that structure diagrams be exported as enhanced metafiles (.emf) which can be read by Inkscape and other image editors. From the "Options" menu, choose "Set Structure Drawing Style" → ACS Style; Draw the structure or reaction diagram; Export the file as PNG or EMF for further processing (see below)
In this type of diagram, first used by the organic chemist Friedrich August Kekulé von Stradonitz, [7] the carbon atoms are implied to be located at the vertices (corners) and ends of line segments rather than being indicated with the atomic symbol C. Hydrogen atoms attached to carbon atoms are not indicated: each carbon atom is understood to ...
[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.
The skeletal formula of the antidepressant drug escitalopram, featuring skeletal representations of heteroatoms, a triple bond, phenyl groups and stereochemistry. The skeletal formula, line-angle formula, bond-line formula or shorthand formula of an organic compound is a type of molecular structural formula that serves as a shorthand representation of a molecule's bonding and some details of ...
It is a matter of taste whether one includes the lone pair in a drawing. Lone pairs of electrons are more common for depictions that emphasize bonding, as in simple gaseous molecules, such as ammonia and nitric oxide. Nonmolecular compounds, e.g. sodium hydride, are best represented with colour-coded spheres that emphasise packing.
