Substitution Pattern at the Double Bond as a Factor in the Green Odour of the C5-C10Alkenols

The type of odour of 47 C₅-C₁₀ alkenols has been compared with the standard fragrance of leaf alcohol [3(Z)-hexen-1-ol] using a four-point scale; the structure–odour relationship shows the similarity of their odour to that of the standard to depend on the substitution pattern at the double bond and the number of carbon atoms in their molecules.
