There is only ONE correct answer to each question.

Which of the following compounds has the highest boiling point? A) CH₃–O–CH₃ B) CH₃CHO C) CH₃COOH D) C₂H₅–NH₂

CH₃–O–CH₃
CH₃CHO
CH₃COOH
C₂H₅–NH₂

Show answer

Correct answer: C. CH₃COOH

Why

Carboxylic acids (CH₃COOH) form strong hydrogen-bonded dimers, giving them notably higher boiling points than ethers, aldehydes, or amines of similar size.
