Document Summary
Isomers are compounds with the same molecular formula but are different from each other. The term is from the greek words isos and meros meaning made of the same parts . Chiral molecules are nonsuperimposable with their mirror images. Molecular chirality arises from a carbon atom attached to four different groups. This carbon atom is called a chirality center (alternatively called chiral center, stereocenter, stereogenic center, asymmetric center). Enantiomer is the nonsuperimposable mirror image of a chiral molecule. A chiral compound has one and only one enantiomer. Assign priorities to the four different groups attached to the chirality center, 1 being the highest priority for the atom with the highest atomic number and 4 being the lowest priority for the atom with the lowest atomic number. Rotate the molecule so that #4 is away from you, so there are 3 groups facing you.
