Unsaturated fatty acids have __________ than saturated fatty acids. Solution lower melting points Unsaturated fatty acids have ( lower melting points ) than saturated fatty acids. Due to presence of olefinic double bonds in unsaturated fatty acid; These molecules do not \"stack\" very well. The intermolecular interactions are much weaker than compared to staurated fatty acids. In results; staurated fatty acids shows greater melting point values than unsaturated fatty acids .
