Thiols

Definition Thiols are organic compounds with the general structure R-SH. They are sulfur analogs of alcohols (R-OH). R can be aliphatic or aromatic. The simplest aliphatic representative is methanethiol, the simplest aromatic is thiophenol (analogue of phenol). Thiols are formally derived from hydrogen sulfide (H2S), in which a hydrogen atom has been replaced by a … Thiols

Ester

Definition Esters are organic compounds formed by the reaction of an alcohol or phenol and an acid such as a carboxylic acid. The condensation reaction releases a water molecule. The general formula of esters is: esters can also be formed with thiols (thioesters), with other organic acids, and with inorganic acids such as phosphoric acid … Ester

Alcohols

Definition Alcohols are a group of organic compounds with the general chemical structure R-OH. The hydroxyl group (OH) is attached to an aliphatic carbon atom. Aromatic alcohols are called phenols. They are a separate group of substances. Alcohols can be obtained as derivatives of water (H 2 O) in which a hydrogen atom has been … Alcohols

Sulfur
