What do molecular formulas and structural formulas have in common?
Lina Baker
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.

What are stuctural isomerism?
Structural isomers are substances having the same formulas but different structures.
Chemical formula but different structural formulas?
Structural isomer
How is molecular formula C3H6 and molecular formula C6H12 related?
Both formulas are possible molecular formulas for the same empirical formula, CH2.
Which compounds have the same molecular formula but different structures?
isomers
What is the advantage of using a structural formula over a molecular formula?
A molecular formula indicates the numbers of atoms of each element in the molecule, but a structural formula also indicates the arrangement of the atoms in the molecule. For example, H2O is the molecular formula for water, but H-O-H is the structural formula, showing how the hydrogen and oxygen atoms are arranged in the molecule.
What are the molecular and structural formulas of water?
H20
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.
Describe the differences between molecular formulas and structural formulas for molecular compounds?
A molecular formula lists the numbers of the atoms of a specific element in a compound. A structural formula is a picture of how the atoms in a specific molecule are connected, with each atom represented by its chemical symbol. For example, oxygen's molecular formula is O2. Its structural formula is O-O.
When are structural formulas used?
Structural formulas are used primarily for organic compounds for which molecular formulas correspond to more than one isomer, or for chemical discussions in which the shapes of molecules are important, such as crystallography.
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.
Do you have a list of common molecular formulas?
Some common molecular formulas include H2O for water, NaCl for salt, C12H22O11 for sugar, and C2H6O for alcohol. The molecular formula for vinegar is CH3COOH.
Has the formula C6H12O6?
The formula given is an approximate molecular formula for hexose sugars, which can have structural formulas distinct from one another.
What are molecules with the same molecular formulas but different structural formulas called?
Molecules with the same molcular formulae but differing structural formulae are called isomers.
What does a structural formula depict that a molecular formula does not?
Structural formulas show a representation of the molecular structure, while chemical formulas do not. This is especially important when multiple compounds have the same chemical formula, but a different molecular structure.
Are the molecular formulas for each of the amino acids the same?
No, in fact people used to think that structural homology was proof for evolution but if you look at the chemistry of two animals with the same structural homology they will be way different
How are organic compounds classified if they have with the same molecular formula but different structural formulas?
they are structual isomers. In alenes they will be e or z isomers ( cis trans0
How are empirical and molecular formulas for a compound created?
An empirical formula is elaborated after the chemical analysis of a compound; for a structural formula more in depth studies are necessary.
