    Hydrolysis of methyl formate gives formic acid and regenerates methanol: HCOOCH 3 → HCOOH + CH 3 OH. Formic acid is used for many applications in industry. Formate esters often are fragrant or have distinctive odors. Compared to the more common acetate esters, formate esters are less commonly used commercially because they are less stable. [5]

    Contributing structures of the carbonate ion. In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, [1] also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.

    en.wikipedia.org/wiki/Chemical_file_format

    A chemical file format is a type of data file which is used specifically for depicting molecular data. One of the most widely used is the chemical table file format, which is similar to Structure Data Format files. They are text files that represent multiple chemical structure records and associated data fields.

  7. Simplified Molecular Input Line Entry System - Wikipedia

    en.wikipedia.org/wiki/Simplified_Molecular_Input...

    The Simplified Molecular Input Line Entry System (SMILES) is a specification in the form of a line notation for describing the structure of chemical species using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the molecules.
