A thiol is a molecule that has a RâSH group. Thiols are like alcohols with an oxygen atom changed with a sulfur one. They have often a very strong and bad smell. Thiols are added to natural gas so that people can smell it. This is because methane does not have a smell but can explode very easily. Thiols are very easy to oxidize. They are also quite acidic, more than alcohols. When the proton is taken away by a base, the thiol can become a nucleophile. It can do reactions like nucleophilic substitution. One of the natural amino acids, cysteine, has a thiol in its structure.
The thiol functional group is similar to the hydroxyl group except the oxygen atom in the hydroxyl group is a sulfur atom in the thiol group. Thiol functional group is also known as a sulfhydryl functional group.Thiol functional groups have formula-SH. Molecules that contain thiol groups are also called mercaptans.. Also known as the carboxyl functional group. The carboxyl group is an ester where one substituent R is a hydrogen atom. The carboxyl group is usually denoted by-COOH. This is the general structure of the thiol functional group.
