What do molecular formulas and structural formulas have in common?

Molecular formulas contain no information about the arrangement of atoms. 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.


Can a molecular formula have subscripts that are multiples of a whole number ratio?

Yes, however most molecular formulas are reduced to Lowest Common Multiples for ease of understanding.


How is molecular formula C3H6 and molecular formula C6H12 related?

Both formulas are possible molecular formulas for the same empirical formula, CH2.


What is the molecular formulas for methane?

CH4


What are the molecular and structural formulas of water?

What is an organic compound with identical molecular formulas that differ in the order the atoms are connected?

Organic compounds that have identical molecular formulas but different structural formulas are called isomers.


Two compounds that have the same molecular formula but different structural formulas are?

Two compounds that have the same molecular formula but different structural formulas are isomers of each other.


What molecular formulas are an empirical formula?

Any molecular formula where the subscripts do not have a common factor that can divide them all. For example: CH4 (methane) is a molecular formula that is also an empirical formula because there is no number (other then one) that can divide both the 4 and the 1. Take ethane as another example. It hasn't the empirical formula which is similar to the molecular formula.


Where can one find more information about molecular formulas?

Information about molecular formulas can be found on chemistry Internet sites or chemistry and physics blogs. They may also be found in chemistry books.


What term is used for molecules that have identical molecular formulas but the atoms in each molecule are arranged differently?

Molecules that have identical molecular formulas but the atoms in each molecule are arranged differently are called isomers.


Why do you use both empirical and molecular formula?

Molecular formulas are used the most often, but empirical formulas do help at times. Often it's just to simplify the molecular formula, but this simplification can often tell you if it's in the same chemical family as other compounds and such.


How are the empirical and molecular formulas for a compuond related?

An empirical formula is a brutto formula; a molecular formula explain the structure of a molecule.
