Question

What is the difference between empirical, molecular and structural formulas?

Answer 1

Hint: Empirical, molecular and structural formulas are going to explain the different parameters of the chemical compound. Without these formulas there is no existence of the chemical in the field of the chemistry.

Complete answer:
- In the question it is asked to write the differences between the empirical, molecular and structural formulas.
- The differences between empirical, molecular and structural formulas are as follows.

S. NO	Empirical Formula	Molecular formula	Structural formula
1	The composition of the compound can be easily expressed by empirical formula.	It is the correct representation of the number of individual elements present in the given molecule.	It is going to explain the correct structural representation of a particular molecule.
2.	It can be calculated by using the weight percentage of the given elements.	It can be calculated by the total atomic weight of the given compound.	It can be drawn by using the molecular formula of the chemical compound.
3.	Empirical formula is not supposed to be used while writing the chemical reaction.	Molecular formulas are going to play a big role while writing the chemical reaction.	It is going to play to explain why a particular compound is going to be formed in major or minor quantity.

Note:
Empirical formula is a simple ratio of the elements present in the particular compound but molecular formula is the multiples of empirical formula of the particular compound. By knowing the structural formula we can define the shape of a particular chemical.
