A molecule may contain any number of stereocenters and any number of double bonds, and each usually gives rise to two possible isomers. A molecule with an integer n describing the number of stereocenters will usually have 2 n stereoisomers , and 2 n −1 diastereomers each having an associated pair of enantiomers .
Discounting isomers that are equivalent under rotations, there are nine isomers that differ by this criterion, and behave as different stable substances (two of them being enantiomers of each other). The most common one in nature ( myo -inositol) has the hydroxyls on carbons 1, 2, 3 and 5 on the same side of that plane, and can therefore be ...
IUPAC name: Common name: Structural formula butanoic acid: butyric acid propanecarboxylic acid: CH 3 (CH 2) 2 COOH : 2-methylpropanoic acid: isobutyric acid isobutanoic acid
The valence isomers are not restricted to isomers of benzene. Valence isomers are also seen in the series (CH) 8. Due to the larger number of units, the number of possible valence isomers is also greater and at least 21: Valence isomers of cyclooctatetraene
