 · Condensed Formula . One particular variation of an empirical or structural formula is the condensed formula. This type of chemical formula is a sort of shorthand notation. The condensed structural formula may omit the symbols for carbon and hydrogen in the structure simply indicating the chemical bonds and formulas of functional groups.
