Unformatted text preview: polar) and insoluble in water. 4. Which of the following are able to hydrogen bond with water: ethanol, 1-decanol, glycerin, sucrose and urea? For each, identify the structural feature which accounts for its ability to hydrogen bond. Explain how H-bonding influences the solubility of each in water; and in hexane. a. All of the above molecules are able to hydrogen bond with water due to their hydroxyl compounds, which they all have in their molecule. The hydrogen has a partial positive charge which bonds to the partial negative of the oxygen, thus able to dissolve in water but not in hexane because it is non-polar. 5. The solubility of the eight ionic salts in water was compared: a. What feature is common to all salts which are soluble in water? b. What feature is to common to salts which are either only slightly soluble in water, or are insoluble?...
