Question
The high solubility of ethanol in water is due to its
A. low boiling point
B. low freezing point
C. covalent nature
D. hydrogen bonding
Solution
The high solubility of ethanol in water is due to its hydrogen bonding. So, the correct answer is D. Hydrogen bonding.
Here's why:
Ethanol (C2H5OH) is a molecule that contains a hydroxyl (-OH) group. The oxygen atom in the hydroxyl group is significantly more electronegative than the hydrogen atom, which results in a polar bond. This polarity allows ethanol to engage in hydrogen bonding with water molecules (H2O), which are also polar.
Hydrogen bonding is a strong type of dipole-dipole interaction that occurs when a hydrogen atom bonded to a highly electronegative atom (like oxygen) is attracted to another electronegative atom in a different molecule.
This hydrogen bonding greatly increases the solubility of ethanol in water.
