Mixing of the components in which of the following pair raises the temperature? — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

CHCl₃ (trichloromethane) and (C₂H₅)₂O (diethyl ether) form strong H-bonds between the acidic CHCl₃ proton and the ether oxygen → exothermic mixing (ΔH_mix < 0) → temperature rises.
