A solution of acetone in ethanol:

Options

  1. Aobeys Raoult's law
  2. Bshows a negative deviation from Raoult's law
  3. Cshows a positive deviation from Raoult's law
  4. Dbehaves like a near ideal solution

Correct answer

C. shows a positive deviation from Raoult's law

Step-by-step solution

A solution of acetone in ethanol shows a positive deviation from Raoult's law because of the miscibility of these two liquids with a difference of polarity and the length of a hydrocarbon chain. Related Theory In an ideal solution, the solvent-solute interaction is the same as a solvent-solvent or solute - solute interaction. This implies both the solute and the solvent takes the same amount of energy to escape to the vapour phase as when they are in their pure states. Caution Raoult's law is apt for describing ide
