Question

Four compounds A, B, C and D having similar molecular masses were tested for their boiling points. It was found that compound C has the highest boiling point of all four. What is the compound C most likely to be?

• A. Hydrocarbon
• B. Haloalkane
• C. Ether
• D. Alcohol

Answer 1

The correct option is D Alcohol

For the compounds having similar molecular masses, alcohols will have the strongest inter molecular force among the given options due to the presence of strong intermolecular hydrogen bonding.
As boiling point is higher for the liquid with stronger inter molecular force, alcohol would have maximum boiling point. Thus option (d) is correct.
