Chapter 10: Unit 4. Isomerism

Isomerism

Isomers are compounds that have the same molecular formula (same number and same kinds of atoms) but that differ in the way the atoms are arranged.

Constitutional isomers: Constitutional isomers are isomers that differ in the connectivity of atoms,, that is in the order in which atoms are attached to each other within molecules.

Conformations: conformations are differing orientations of the same molecule made possible by free rotation about single bonds in the molecule.

There is another type of isomers where mirror image is considered to be the base of difference between two compounds. They are called stereoisomers. We will discuss it in later chapter.
