Question

Which of these hydrocarbons are most likely to be soluble in water?
Options
A Ethylene
B Benzene
C Paraffin
D Acetylene
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Acetylene (ethyne) is slightly more polarizable and has a small, linear structure. While hydrocarbons are generally nonpolar, acetylene has a small degree of polarity due to the sp-hybridized carbon and acidic hydrogen, making it slightly more soluble than other hydrocarbons. Among the options, it is the most soluble in water.

Hint

Smaller, more polarizable molecules with triple bonds can have slight interactions with water.
