Parentheses chemistry

WebChemistry and physics. Parentheses are used in chemistry to denote a repeated substructure within a molecule, e.g. HC(CH 3) 3 or, similarly, to indicate the stoichiometry of ionic compounds with such substructures: e.g. Ca(NO 3) 2 (calcium nitrate). Web15 Jun 2024 · This formula can also be simplified using parentheses: CH3(CH2)3CH3, indicating that between the two CH3there are three CH2. The other two isomers of pentane, however, are a bit more complicated: CH3CH2CH (CH3)2, for 2-methylbutane, and C (CH3)4for 2,2-dimethylpropane or neopentane.
