The key difference between eugenol and isoeugenol is that eugenol has a clove-like odour, whereas isoeugenol has a floral odour. Eugenol and isoeugenol are structural isomers of each other. We can distinguish them from each other through their odour because both these are aromatic compounds.

Is eugenol polar or non polar?
Figure 4 shows the Solubility of the eugenol +1- octanol + water system in accordance with the principle of polarity since eugenol has a non-polar tendency while ethanol has nonpolar properties, so eugenol is soluble in 1-octanol, whereas Octanol tends to dissolve with water (polar) and eugenol is slightly soluble in …
How eugenol is used as the painkiller?
Eugenol inhibits N-methyl-d-aspartate (NMDA) receptors which are involved in pain sensitivity (Aoshima and Hamamoto, 1999 โถ). Eugenol is similar in chemical structure to capsaicin and therefore its effect on a vanilloid receptor should not be ignored (Yang et al., 2003 โถ).
