XDrawChem is a free software program for drawing chemical structural formulas, available for Unix and macOS. It is distributed under the GNU GPL. In Microsoft Windows this program is called WinDrawChem. [1]
An example is the condensed molecular/chemical formula for ethanol, which is CH 3 −CH 2 −OH or CH 3 CH 2 OH. However, even a condensed chemical formula is necessarily limited in its ability to show complex bonding relationships between atoms, especially atoms that have bonds to four or more different substituents.
Writing SMILES for substituted rings in this way can make them more human-readable. Branches may be written in any order. For example, bromochlorodifluoromethane may be written as FC(Br)(Cl)F, BrC(F)(F)Cl, C(F)(Cl)(F)Br, or the like. Generally, a SMILES form is easiest to read if the simpler branch comes first, with the final, unparenthesized ...
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

The free, open-source program called WinDrawChem (the Windows version of XDrawChem) appears to work well. ( link ) Unix-like users should follow the XDrawChem article link. The configuration is extremely limited and post-processing is likely required.
Render chemical formulas using HTML. Alternatively, you can use <chem>...</chem>, using mhchem LaTeX notation to generate formulas. Up to 25 unnamed ordered parameters can be used with automatic detection of subscripts and superscripts. Template parameters [Edit template data] This template prefers inline formatting of parameters. Parameter Description Type Status Link link Make the formula ...
Spaces within a formula must be directly managed (for example by including explicit hair or thin spaces). Variable names must be italicized explicitly, and superscripts and subscripts must use an explicit tag or template. Except for short formulas, the source of a formula typically has more markup overhead and can be difficult to read.
