Account for the Observation That Ethyl Alcohol, OH

question 76

Multiple Choice

Account for the observation that ethyl alcohol, OH, dissolves readily in water but dimethyl ether, C OC , which has the same number and kinds of atoms, does not.

• A) The hydrogens on the dimethyl ether surround the molecule, shielding the inner atoms from interacting with the water.
• B) Because the carbons arrange themselves in a straight line, the ethanol can interact more easily with more water molecules, thus increasing its solubility.
• C) The high electronegativity of the carbon-oxygen-carbon bond on dimethyl ether creates a strong dipole charge on the ends of the molecule, making it highly soluble in water.
• D) Because dimethyl ether lacks an -OH group, it is significantly less polar than is ethyl alcohol and is not readily soluble in water.
