Nomenclature of Mercaptans
Mercaptans can be named by naming the parent compound immediately followed by the word thiol. The -SH group can also be named as a substituent using the group name, sulfhydryl. Mercaptans can also be named by naming the carbon group as a separate word followed by the word mercaptan.
- CH3-SH
- methanethiol
- sulfhydrylmethane
- methyl mercaptan
