The correct order of boiling points of N-ethylethanamine (I), ethoxyethane (II) and butan-2-ol (III) is
- A III \( < \) II \( < \) I
- B II \( < \) III \( < \) I
- C II \( < \) I \( < \) III
- D III \( < \) I \( < \) II
Answer & Solution
Correct Answer
(C) II \( < \) I \( < \) III
Step-by-step Solution
Detailed explanation
Hint : Butan-2-ol shows stronger H-bonding than N-ethylenthanamine. Ethoxyethane involves dipole association, weaker than \(\mathrm{H}\)-bonding
