Naphthalene is an organic compound with formula C 10 H 8.It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. All Rights Reserved. Solution for 1. There is one precaution to consider in using the formic acid/hexane method as a sep- aration procedure for naphthalene metabolites. Ethanol is greater soluble because of the fact it has a hydroxyl group which could hydrogen bond with water. Ethyl acetate and Naphthalene are both non-polar compound, thus Naphthalene dissolve in Ethyl acetate the best than other solvents. The compound sublimes (turns from a solid to a gas) slowly at room temperature, producing a vapor that is highly combustible. Yes, naphthalene is soluble in cyclohexane, and here's why that happens. Naphthalene (NAF-thuh-leen) is a white crystalline volatile solid with a characteristic odor often associated with mothballs. How much money do you start with in monopoly revolution? Indicate the kinds of intermolecular forces that occur… Therefore, their bonding was strong and effective. Ethylene Glycol GPA RR-117 [7], RR-149 [8], RR-137 [9] contain equilibrium data for solubility of methane, propane, n-heptane, ABSTRACT This paper compares the solubility of hydrocarbons in several physical solvents such solubility data very closely and the be used to investigate factors affecting hydrocarbon solubility in physical solvents. and both napthalene and hexane are non-polar molecules.
