According to Raoult&#39;s law,  The vapor pressure exerted by component in a solution is proportional to the mole fraction of that component.  Raoult&#39;s law is not applicable under the following assumption/condition.-A-No component is concentrated at the surface of the solution.B-The component molecules are non polar and are of almost equal size.C-In the formation of solution, chemical combination/molecular association between unlike molecules takes place.D-The attractive forces between like and unlike molecules are almost equal.-C-In the formation of solution, chemical combination/molecular association between unlike molecules takes place.

APTITUDE CRACK · Accepted Answer

The correct option is  C In the formation of solution, chemical combination/molecular association between unlike molecules takes place. Raoult&#39;s law is based on several assumptions, and it may not be applicable under certain conditions. One of the conditions under which Raoult&#39;s law is not applicable is: In the formation of solution, chemical combination/molecular association between unlike molecules takes place. When chemical combination or strong molecular association occurs between unlike molecules, the behavior of the solution deviates from ideal behavior. Raoult&#39;s law assumes ideal behavior, where the interactions between solute solvent molecules are similar to solute solute and solvent solvent interactions. If chemical combination or strong association occurs, it alters the vapor pressure of the solution, making Raoult&#39;s law invalid. Therefore, the correct option is: In the formation of solution, chemical combination/molecular association between unlike molecules takes place.
