Question Detail
Question
Which of the following compounds has the lowest boiling point?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Butanenitrile (butyronitrile) has the lowest boiling point because nitriles have weaker intermolecular forces (dipole-dipole) compared to alcohols and carboxylic acids (which have hydrogen bonding) and esters (which have dipole-dipole interactions but higher molecular weight).
Hint
