The comparison of hydrogen-bond dissociation of cis-9-octadecenoic acid and trans-9-octadecenoic acid in the inactive solvents by means of IR absorption spectroscopy

The comparison was made of the dissociation degree values for the hydrogen-bond multimers of two geometrical isomers: cis- and trans-9-octadecenoic acids. The measurements were performed for the series of solutions of the discussed substances in the inactive solvents: carbon tetrachloride and n-hexane. The applied technique was ir absorption spectroscopy. The general statement is that trans-9-octadecenoic acid in both carbon tetrachloride and n-hexane shows greater tendency towards dissociation of multimers than cis-9-octadeconoic acid.
