Marjolein Snippe Jul 26, 2022:
nomenclature Just in case it is the "one" part getting you confused: -one indicates that this is a ketone, a class of organic molecules (just like -ol indicates that the molecule is an alcohol and -al indicates it is an aldehyde). For a bit of background information, see for example
