What role does the molecular interaction play in a solution of alcohol and water?

Options

  1. AMolecular interaction in a solution of alcohol and water is negligible, and they do not affect each other's pr
  2. BMolecular interaction leads to complete separation of alcohol and water in a solution, with no mixing or inter
  3. CThere is strong hydrogen bonding in alcohol molecules as well as water molecules. On mixing the molecular inte
  4. DMolecular interaction causes alcohol and water to repel each other, preventing them from forming a solution.

Correct answer

C. There is strong hydrogen bonding in alcohol molecules as well as water molecules. On mixing the molecular inte

Step-by-step solution

Correct Option is : (C) There is strong hydrogen bonding in alcohol molecules as well as water molecules. On mixing the molecular interactions are weakened. Hence, they show positive deviations from ideal behaviour. As a result, the solution will have higher vapour pressure and lower boiling point than that of water and alcohol.
