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.
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.
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
Substances having the same chemical formula but different structures are called?
Two molecules with identical molecular formulas but that have different structures are called isomers. Fuels such as gasoline are nonpolar and high in energy because they are largely composed of hydrocarbons.
Why do chemists use structural formulas for organic compounds rather then molecular formulas such as C5H12?
Starting with C4H10, hydrocarbons can have multiple configurations, called isomers, for the same formula. These isomers are regarded as different compounds and have different physical and chemical properties. In such cases simply using the chemical formula would be ambiguous.
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.
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. Isomers are compounds with the same number and types of atoms but arranged differently. An example is ethanol (C2H6O) and dimethyl ether (C2H6O), both have the same molecular formula but different structural formulas.
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.
What is an organic compound with identical molecular formulas that differ in the order the atoms are connected?
Isomers are organic compounds that have the same molecular formula but different structural arrangements of atoms. These structural isomers can differ in the order the atoms are connected, leading to different properties and reactivities. An example of structural isomers are n-pentane and isopentane, both with the molecular formula C5H12.
What are the molecular and structural formulas of water?
H20
Chemical formula but different structural formulas?
Isomers are compounds with the same molecular formula but different structural formulas. This means they have the same number of atoms of each element but arranged in a different way. Isomers can have different physical and chemical properties as a result of their different structures.
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.
How are organic compounds classified if they have with the same molecular formula but different structural formulas?
Organic compounds with the same molecular formula but different structural formulas are classified as structural isomers. These isomers have different arrangements of atoms within their structures, which can lead to differences in their physical and chemical properties. Examples of structural isomers include chain isomers, functional group isomers, and positional isomers.

Can molecules with molecular formulas c4h10 and c4h10o be isomers of one another Why or why not?
Yes, molecules with molecular formulas C4H10 and C4H10O can be isomers of one another. C4H10 represents butane, whereas C4H10O represents 1-butanol. These two molecules have different structures due to the presence of an oxygen atom in 1-butanol, making them structural isomers.
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
What are stuctural isomerism?
Structural isomerism is a type of isomerism where the isomers have the same molecular formula but differ in the connectivity of atoms within the molecule. This results in different structural arrangements and different chemical and physical properties among the isomers. There are different types of structural isomerism, such as chain isomerism, positional isomerism, and functional group isomerism.
