COMEDK · Chemistry · 26. Alcohols Phenols and Ethers
Arrangement of following compounds based on their boiling points in the increasing order. \(n\)-butane, 1-butanol, ethoxyethane and 1-propanol will be
- A 1-propanol \(>n\)-butane \(>\) ethoxyethane \(>\) 1-butanol
- B \(n\)-butane \( < \) ethoxyethane \( < 1\)-propanol \( < 1\)-butanol
- C \(n\)-butane \( < 1\)-propanol \( < \) ethoxyethane \( < 1\)-butanol
- D 1-propanol \( < n\)-butane \( < \) ethoxyethane \( < 1\)-butanol
Answer & Solution
Correct Answer
(B) \(n\)-butane \( < \) ethoxyethane \( < 1\)-propanol \( < 1\)-butanol
Step-by-step Solution
Detailed explanation
Boiling point increases with increase in molecular mass so, 1-butanol has higher boiling point than -propanol. Unlike alcohols, ethers do not form hydrogen bonds thus, they have lower boiling points than the corresponding alcohols. Due to weak dipole-dipole interactions, the…
