Question
Give reason Ethanol has higher boiling point then that of methoxy methane.
✓

Answer

⇒ The molecules of ethanol are associated due to the formation of intermolecular hydrogen bond. Hence, more energy is required to break the inter molecular force of attraction between ethanol molecules, Therefore the boiling point of ethanol is relatively high. Whereas the methoxymethane molecules can readily convert in to vapour because only weak Van der waals force of attraction exist between them. Hence, its boiling point is lower than that of ethanol.
