what do round brackets in an chemical equation mean?
molecules with multiple functional groups that are the same
molecules with multiple functional groups that are the same may be expressed by enclosing the repeated group in round brackets. for example, isobutane may be written (ch)ch. this condensed structural formula implies a different connectivity from other molecules that can be formed using the same atoms in the same proportions (isomers). the formula (ch)ch implies a central carbon atom connected to one hydrogen atom and three ch groups. the same number of atoms of each element (10 hydrogens and 4 carbons, or ch) may be used to make a straight chain molecule, "n"-butane: chchchch.

chemical equation









































a chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side. the coefficients next to the symbols and formulae of entities are the absolute values of the stoichiometric numbers. the first chemical equation was diagrammed by jean beguin in 1615.
