Web21 Feb 2024 · Sometimes a formula can be written in a way that gives an indication of the structure. For example, acetic acid contains 2 carbons, 4 hydrogens, and 2 oxygens, so could be given as C 2 H 4 O 2 — but is more usually written as CH 3 COOH, to emphasise the structure: Equations. A chemical equation shows a reaction taking place. For simple molecules, a condensed (or semi-structural) formula is a type of chemical formula that may fully imply a correct structural formula. For example, ethanol may be represented by the condensed chemical formula CH 3 CH 2 OH, and dimethyl ether by the condensed formula CH 3 OCH 3.
