What is a structural formula? What is the difference between a structural formula and a molecular model?
The structural formula of a chemical compound is a graphic representation of the molecular structure, showing how the atoms are arranged. The chemical bonding within the molecule is also shown, either explicitly or implicitly. Unlike chemical formulas, which have a limited number of symbols and are capable of only limited descriptive power, structural formulas provide a complete geometric representation of the molecular structure.
For example, many chemical compounds exist in different isomeric forms, which have different enantiomeric structures but the same chemical formula.
A structural formula is able to indicate arrangements of atoms in three...
