Acid-catalyzed dehydration of propan-1-ol Steps:

• Recognize CH3CH2CH2OH as propan-1-ol, a primary alcohol.
• Note that warming with little concentrated H2SO4 favors ether formation over alkene dehydration.
• Understand that standard reaction yields dipropyl ether (acyclic) via intermolecular SN2.
• Conclude no cyclic compound forms under these conditions, as chain length prevents intramolecular cyclization.
