When the ________ molecules of ethanol,C₂H₅OH,are added to water,the ethanol molecules ________. A)nonpolar;are attracted to the nonpolar water molecules B)polar;form hydrogen bonds with the polar water molecules C)polar;form covalent bonds with the polar water molecules D)nonpolar;are not attracted to the polar water molecules

Question

Quizplus · Accepted Answer

Ethanol contains polar hydroxyl (-OH) and nonpolar carbon-hydrogen (C-H) regions. When ethanol is added to water, the polar hydroxyl region of ethanol forms hydrogen bonds with the polar water molecules, while the nonpolar C-H region is repelled by the polar water molecules. Therefore, ethanol molecules form hydrogen bonds with water molecules, and since hydrogen bonds are a type of polar interaction, the ethanol molecule is considered polar.
