WebIn organic chemistry, a thiol is a compound that contains the –SH functional group, which is the sulfur analog of a hydroxyl or alcohol group. The functional group is referred to as either a thiol group or a sulfhydryl group. Thiols are more traditionally referred to as mercaptans. Thiols and alcohols have similar molecular structure ... WebThiols, or sulfur analogs of alcohols, are sometimes referred to as mercaptans. In naming these compounds, the suffix -thiol is appended to the name of the appropriate hydrocarbon; e.g., CH3CH2CH2CH2SH is named butanethiol. The prefix mercapto- is placed before the name of a compound if the ―SH group is to be named as a substituent, as in …
