Answer is: it can be endothermic when the amount of energy needed to break the intermolecular forces in the solute is larger than the amount of energy given off by formation of intermolecular forces in the mixture, so solution must be heated.
In ideal solution 
 the forces of attraction between the solute-solute and the solvent-solvent and solute-solvent molecules are the same.
