3.1 ALCOHOLS
An alcohol is any molecule with an
alcohol functional group. An alcohol
group consists of an oxygen atom
Figure 3.1: An alcohol group
bound to both the carbon backbone
on one end and a hydrogen atom on the other end (see figures 3.1
and 3.2). In general, alcohol molecules have names ending with the
suffix –ol. For instance, menthol, terpinen-4-ol, citronellol, geraniol,
and linalool are examples
of monoterpene alcohols.
Santalol,
isovalencenol,
khusimol,
cedrol
(also
known as eudesmol), and
patchoulol
(also
known
as patchouli alcohol) are
sesquiterpene alcohols. One
exception to this naming rule
is the compound eucalyptol,

which is actually an epoxide
found in peppermint oil
(a type of ether).
