Multiple Choice
Which of the following factors is most important in determining the solubility of a compound in water?
A
Polarity of the compound
B
Melting point of the compound
C
Color of the compound
D
Molecular weight of the compound
Verified step by step guidance
1
Understand that solubility in water is primarily influenced by the ability of a compound to interact with water molecules, which are polar.
Recognize that polarity refers to the distribution of electrical charge over the atoms joined by the bond. Polar compounds tend to dissolve well in polar solvents like water due to dipole-dipole interactions.
Consider that non-polar compounds do not interact favorably with water, leading to low solubility. Therefore, the polarity of a compound is a key factor in its solubility in water.
Evaluate other factors such as melting point, color, and molecular weight. These factors can influence solubility but are not as directly impactful as polarity.
Conclude that among the given options, the polarity of the compound is the most important factor in determining its solubility in water.
