Answer 2

In chemistry, formulas are the numbers and alphabets that represent the molecules and their population in a particular compound.

Structural Formula

• The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods).

• It shows how the atoms are possibly arranged in the real three-dimensional space. Meaning the X, Y, and the Z axes.
• It gives us a clear picture of the molecule it represents and helps us to understand the chemistry of the molecule

Condensed Formula

• The condensed formula of a molecule, as the name says is a shortened formula of the structural formula.
• Here, symbols of atoms are listed in the sequence as they appear in the structure, but the bond dashes are limited.
• Usually, the horizontal bonds are retained and the vertical ones are omitted.

Bond line or Zig-Zag Formula

• It is a representation of the molecular structure, where the covalent bonds are represented in lines. Each bond order is represented by a line.
• A single bond is represented by a single line. A double line indicates the presence of a double bond or also, two parallel lines indicate a double bond.
• A triple line indicates a triple bond. Functional groups are mentioned in their respective Carbon position by extending the line.

Different types of formulas help us in different contexts, below is the picture are the various representations of molecules as given in the table.
