Description

Butanediol Structural Isomers

Butanediol, also called Butylene Glycol, may refer to any one of four stable Structural Isomers:

  • 1,2-Butanediol
  • 1,3-Butanediol
  • 1,4-Butanediol
  • 2,3-Butanediol

Gem-Butanediols

There exists as well two Geminal Diols (Gem-diols), which are less stable:

  • 1,1-Butanediol, hydrate of butanal
  • 2,2-Butanediol, hydrate of butanone

Isobutylene Glycols

Isobutylene Glycol may be considered a kind of Butylene Glycol, similarly to Butane historically including n-Butane and Isobutane. The modern name for the closely related type of compounds is Methylpropanediol. There are two stable structural isomers:

  • 2-Methylpropane-1,2-diol
  • 2-Methylpropane-1,3-diol

and one unstable Geminal Diol:

  • 2-Methylpropane-1,1-diol (not a glycol)

These three Methylpropanediols are Structural Isomers of Butanediols. They are not chiral.
