Pentane: CH3CH2CH2CH2CH3
Methanoic acid: CH3COOH
2-methylbutanoic acid: CH3CH(CH3)CH2COOH
A structural formula distinguishes between isomers by showing the specific arrangement of atoms. Isomers have the same molecular formula but different structural formulas. For example, pentane, methanoic acid, and 2-methylbutanoic acid all have the molecular formula C5H12O2. However, their structural formulas are different, reflecting the different ways the atoms are connected. This difference in arrangement leads to different physical and chemical properties, defining them as distinct compounds.
