Question
Which of the following compounds is the least soluble in water?
Correct Answer
Option D is the correct answer.
Detailed Explanation
Solubility of alcohols in water decreases as the hydrocarbon chain length increases (more nonpolar character). 1-Butanol (CH3CH2CH2CH2OH) is the least soluble among the options. HOCH2CH2OH (ethylene glycol) is highly soluble.
Hint
How does chain length affect water solubility of alcohols?
