Correct Answer
D>C>A>B
Detailed Explanation
- Pentan-1-ol (D) - highest boiling point due to strong hydrogen bonding.
- Pentanal (C) - next due to dipole-dipole interactions.
- Ethoxyethane (A) - lower boiling point owing to weak van der Waals forces.
- n-Butane (B) - lowest boiling point due to its simpler structure and lower molecular weight.
