Solubilities have been determined at 30, 35 and 40° C for biphenyl in carbon tetrachloride, cyelohexane, n-hexane, n-heptane and n-octane, and tor naphthalene in benzene, cyclohexane, toluene, ethylbenzene, carbon tetrachloride and n-hexane.Results of these measurements, combined with published data at 25 °C, are used to calculate the Wilson interaction parameters and to predict … Naphthalene is a nonpolar compound. As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of benzene rings. Solution for 1. All Rights Reserved. The C-H bonds that make up the molecule are considered to be non-polar becasue of the small difference in electronegativity between the two atoms. There is one precaution to consider in using the formic acid/hexane method as a sep- aration procedure for naphthalene metabolites. The experimental data were correlated with the Wilson model, Apelblat equation, and λ-h model. It is soluble in cyclohexane (like benzene), but not as soluble in n-hexane. Naphthalene is an aromatic hydrocarbon and nonpolar. 00. Is naphthalene soluble in water or hexane? Yes, the naphthalene will partially sublime, but your sublimation temp is way too low, I think it's 80 C. The solution is to use a cold finger to catch the naphthalene. Ethyl acetate and Naphthalene are both non-polar compound, thus Naphthalene dissolve in Ethyl acetate the best than other solvents. 1) Malic Acid in Water 2) Naphthalene in Water 3) Amphetamine in Ethyl Alcohol 4) Aspirin in Water 5) Succinic Acid in Hexane 6) Ibuprofen in Diethyl Ether 7) 1-Decanol in Water For some of them, I already have the answer and for others, I'm not sure. Napthalene is soluble in hexane because “like dissolves like” and both napthalene and hexane are non-polar molecules. the final rule is that if a compound has greater effective than 4 carbon atoms that's insoluble.
