Final answer:
Isomers are compounds that have the same molecular formula but different structural formulas. There are two main types of isomers: structural isomers and stereoisomers.
Step-by-step explanation:
Isomers are compounds that have the same molecular formula but different structural formulas. There are two main types of isomers: structural isomers and stereoisomers.
Structural Isomers:
Structural isomers are organic compounds that have the same molecular formulas but different structures. They differ in how the atoms are connected to each other. For example, two pentane molecules can be structural isomers if they differ only in the location of a methyl group.
Stereoisomers:
Stereoisomers are isomers in which the order of atom bonding is the same, but the arrangement of atoms in space is different. They can be further classified into geometric isomers and enantiomers. Geometric isomers have a different arrangement of atoms around a double bond, while enantiomers are mirror images of each other.
