b) H2O. Water is the most common solvent, ... Thermodynamically for a substance to be soluble the Gibbs Free Energy change for the process must be negative. From the given choices, benzene is the most nonpolar solute and will be the most soluble solute in nonane. The benzene carboxylic acid is only slightly soluble… Water, being a polar solvent, doesn’t dissolve benzene. D) H2SO4. Benzene is non-polar and it is used to dissolve non-polar solutes (remember like dissolves like). Salts of alkali metals (and ammonium), as well as those of nitrate and acetate, are always soluble. In contrast, a non-polar solute such as naphthalene is insoluble in water, moderately soluble in methanol, and highly soluble in benzene. Solubility Chart. Octane is nonpolar, it is most likely to be dissolved in benzene. How is Polarity of a Molecule Determined. COVID-19 is an emerging, rapidly evolving situation. H2O, NH3, and ethanol are very polar (regions of partial negative/positive charges) and NaCl is ionic, so all four dissolve in water. cyclohexane (C6H12); benzene (C6H6) sodium chloride (NaCl) would be the least soluble. Benzene | C6H6 | CID 241 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. Figure 9.2.3 Water is immiscible with with perfluoroheptane (and most halogenated compounds) . On the basis of polarity and hydrogen bonding which solute would be the most soluble in benzene C6H6? Adding more benzene results in the separation of an upper layer consisting of benzene with a small amount of dissolved water (the solubility of water in benzene is only 178 mg/100 mL of benzene). 1. aldehydes 2. alcohols 3. ketones 4. carboxylic acids Related Posts. Which group is the most soluble in water (assuming masses and number of carbons are equivalent)? propane (C3H8) will be quite soluble … C) CH3CH2CH2CH3. Benzene is an organic chemical compound with the molecular formula C 6 H 6.The benzene molecule is composed of six carbon atoms joined in a planar ring with one hydrogen atom attached to each. THANKS! Benzene is soluble in non-polar solvents, but not soluble in polar solvents. Its solubility percentage in water is 0.18%, which confirms that it is not soluble in water. a) CH3OH. As it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon.. Benzene is a natural constituent of crude … This is because hexane is a non-polar molecule and benzene is also... See full … Get the latest public health information from … Benzene ({eq}\rm C_5H_6{/eq}) is more soluble in hexane than ethanol. The solubility chart shows the solubility of many salts.
