Which of the following compound has the lowest boiling point?
Show Hint
- Carbon disulfide
- Water
- Ethanol
- Benzene
- Chloroform
The Correct Option is A
Solution and Explanation
Among the given compounds, carbon disulfide (CS\(_2\)) has the lowest boiling point. This is due to its weak intermolecular forces (van der Waals forces), compared to the hydrogen bonding present in water, ethanol, and chloroform.
Thus, the correct answer is (A).
