Concept Introduction:
The organic compounds can be represented in two-dimensional structural format known as Structural Formula. From this we can identify the bonding between various atoms present in the molecule. Condensed structural formula and expanded structural formula are two types of structural formulas.
Expanded structural formula is the one in which all the atoms in molecule and all bonds connecting the atoms are shown clearly. If a molecule is represented using expanded structural formula means more space will be occupied.
Condensed structural formula basically uses grouping of atoms. The central atom and the atoms that are connected to them are considered as groups and they are written. This is a very short hand representation of structural formula.
Skeletal structural formula is also used in
