Nomenclature and Symbolism for Amino Acids and Peptides
WebA and B are both chiral molecules, and they are enantiomers of each other. The substance 2-propanol, unlike 2-butanol, is not a chiral molecule. Carbon #2 is bonded to two identical substituents (methyl groups), not 4 different groups, and so it is not a chiral center. It has an internal mirror plane.
