Mixture(s) showing positive deviation from Raoult's law at 35 o C is (are)

Options

  1. ACarbon tetrachloride + methanol
  2. BCarbon disulphide + acetone
  3. CBenzene + toluene
  4. DPhenol + aniline

Correct answer

A. Carbon tetrachloride + methanol

Step-by-step solution

A] H-bonding of methanol breaks when C C l 4 is added so bonds become weaker, resulting positive deviation. B] Mixing of polar and non-polar liquids will produce a solution of weaker interaction, resulting positive deviation C] Ideal solution D] -ve deviation because stronger H-bond is formed.
