WebThiols are a family of compounds that contain the sulfhydryl group (-SH). Thiol = R-SH. An alcohol molecule can be compared to a water molecule. In an alcohol molecule, the hydroxyl oxygen and the two atoms bonded to it are all in the same plane and have a bond angle of approximately 104 o. This is very similar to a water molecule.
