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.
Both formulas are possible molecular formulas for the same empirical formula, CH2.
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.
Structural isomer
Structural isomers are substances having the same formulas but different structures.
Two compounds that have the same molecular formula but different structural formulas are isomers of each other.
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.
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.
Stereoisomers are isomeric molecules that have the exact same molecular formula, but a different three dimensional position. A conformer is a set of stereoisomers.
The formula given is an approximate molecular formula for hexose sugars, which can have structural formulas distinct from one another.
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.
An empirical formula is elaborated after the chemical analysis of a compound; for a structural formula more in depth studies are necessary.
Both formulas are possible molecular formulas for the same empirical formula, CH2.
the answer is : 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.
