Class	Description
nitrosamine	N-Nitroso amines, compounds of the structure R2NNO. Compounds RNHNO are not ordinarily isolable, but they, too, are nitrosamines. The name is a contraction of N-nitrosoamine and, as such, does not require the N locant.
secondary alcohol	A secondary alcohol is a compound in which a hydroxy group, -OH, is attached to a saturated carbon atom which has two other carbon atoms attached to it.
diol	A compound that contains two hydroxy groups, generally assumed to be, but not necessarily, alcoholic. Aliphatic diols are also called glycols.
