A structural formula is a simplified model that cannot represent certain aspects of chemical structures. For example, formalized bonding may not be applicable to dynamic systems such as delocalized bonds.

As you can see, the structural formula shows how each atom connects to each other in the molecule. It also details the types of bonds (single, double, or triple bonds).

In condensed structural formulas the bonds to each carbon are omitted, but each distinct structural unit (group) is written with subscript numbers designating multiple substituents, including the hydrogens.

There are various levels of condensed structural formulas, and there are some rules about how formulas are properly condensed. The condensed formula of the molecule comprised of three carbons and …

Structural formulas identify the location of chemical bonds between the atoms of a molecule. A structural formula consists of symbols for the atoms connected by short lines that represent chemical …
