✦Types of chemical Formula are :-

☛Empirical formula:- The formula which denotes simple the ratio of the number of atoms of different elements present in the molecule of that compund is Known as Empirical formula.

• For example:- In a molecules of Ethane (C2H6) ,there are two atoms of carbon and 6 atoms of Hydrogen present.Thus their simple ratio will be 1:3 ,Therefore the empirical formula of Ethane will be CH3 .

☛ Molecular formula:-The formula which express the actual number of atoms of element present in a molecule is known as molecular formula.

• For example:- The molecular formula of water is H2o.Molecular formula is either equal to empirical formula or it's simple whole number.

☛Structural formula :- The formula which shows the arrangement of atoms present in molecule of compund or configuration in the molecules of a compund known as structural formula.

☛ Rational formula :- The short form of structural formula is known as rational formula.

Answer 2

Answer:

• A chemical formula is a simple representation, in writing, of a three dimensional molecule that exists.
• A chemical formula describes a substance, down to the exact atoms which make it up. 

There are three major types of Chemical Formulas

• Molecular formulas
• structural formulas
• empirical formulas.
