The molar enthalpy of vapourisation of acetone is less than that of water. Why ? |
|
Answer» Solution :Amount of heat required to VAPORISE one mole of a liquid at constant TEMPERATURE and under standard pressure (1 bar) is called its molar enthalpy of vaporisation `Delta_("vap") H^( THETA )`. Molar enthalpy of vaporisation of water is more than of acetone because there is STRONG hydrogen bonding in `H_(2) O` molecule. |
