Question

Which one of the following is most soluble in water?

A) CH₃OH
B) CH₃CH₂CH₂OH
C) CH₃CH₂OH
D) CH₃CH₂CH₂CH₂OH
E) CH₃CH₂CH₂CH₂CH₂OH

Answer 1

Substances that dissolve in water are typically polar or have the ability to form hydrogen bonds with water molecules. Methanol (CH3OH) is more soluble in water than ethanol (CH3CH2OH) due to its smaller size and better ability to hydrogen bond with water.

Step-by-step explanation:

Water is considered a polar solvent. Substances that dissolve in water are typically polar or have the ability to form hydrogen bonds with water molecules. Methanol (CH3OH) and ethanol (CH3CH2OH) are both polar molecules and can form hydrogen bonds with water, making them soluble in water. However, methanol (CH3OH) is more soluble in water than ethanol (CH3CH2OH) due to its smaller size and better ability to hydrogen bond with water. Therefore, the correct answer is A) CH3OH.
