Question

Which one of the following organic compounds has highest boiling point?

• A. Pentan-1-al
• B. Pentan-1-ol
• C. n-pentane
• D. Ethoxyethane

Answer 1

Answer: (B)

Pentan-1-ol has the highest boiling point among these
$\underset{(bp103^{\circ }C)}{\text{Pentan-1-al}}\underset{(bp137^{\circ }C)}{\text{Pentan-1-ol}}\underset{(bp36^{\circ }C)}{\text{n - pentane}}\underset{(bp35^{\circ }C)}{\mathrm{Ethoxyethane}}$
