Cyclohexane with iodine
WebIt will be noted that the iodine values obtained when using either solvent are in good agreement and also that the precision of the determination is not affected when cyclohexane + glacial acetic acid is used in place of carbon tetrachloride. WebApr 22, 2024 · 1) Iodine, being a non-polar substance, should dissolve the most in nonpolar solvents. Yet diethyl ether the best solvent for iodine. 2) Toluene and n-Hexane, both being hydrocarbons, should have similar solubilities of iodine. Yet the solubility of Iodine in Toluene almost 20 times that of n-Hexane. How do we qualitatively predict these results?
