The grassy smell of cut grass, for example, is not due to just hexanal or hexanol (which is practically odorless (I used to work with it too)) as McGee states, but is primarily (but not only) due to cis-3-hexenol and cis-3-hexenal, the latter of which is somewhat unstable and isomerizes into trans-2-hexenal.
