The molar enthalpy of vaporisation of acetone is less than that of water. Why ? |
| Answer» Solution :Amount of heat REQUIRED to vaporise one mole of a liquid at constant tempeature and under standard pressure (1 BAR) is called its molar enthalpy of vaporisation `Delta_("vap") H^(Θ)`. Molar enthalpy of vaporisation of WATER is more than that of acetone because there is strong hydrogen bonding in `H_(2)O` molecule | |
