What is the difference between simplest formula and molecular formula

Why is the number of protons and electrons equal in an atom? Question 2b Question a Question c0a6c. See all questions in Basic Atomic Structure. Because of this, one molecular formula can describe a number of different chemical structures. A structural formula is used to indicate not only the number of atoms, but also their arrangement in space. A structural formula is not as compact and easy to communicate, but it provides information that the molecular formula does not about the relative positioning of atoms and the bonding between atoms.

Compounds that share a chemical formula but have different chemical structures are known as isomers, and they can have quite different physical properties. Boundless vets and curates high-quality, openly licensed content from around the Internet.

This particular resource used the following sources:. Skip to main content. Atoms, Molecules, and Ions. Molecular formulas tell you how many atoms of each constituent are in a compound, and empirical formulas tell you the simplest or most summary ratio of elements in a compound. The molecular formula gives us the actual number of different atoms in a molecule. And, the empirical formula is exact when describing ionic compounds, which cannot be broken into a single molecule unit.

Empirical Formula — It is the simplest formula for a compound which is defined as the ratio of subscripts of the smallest possible whole number of the elements present in the formula. Molecular Formula — It is the formula derived from molecules and is representative of the total number of individual atoms present in a molecule of a compound. Differences between Empirical Formula and Molecular Formula: Empirical Formula — It is the simplest formula for a compound which is defined as the ratio of subscripts of the smallest possible whole number of the elements present in the formula.
