MCQ
A solution of acetone in ethanol
  • A
    obeys Raoult's law
  • B
    shows a negative deviation from Raoult's law
  • ✓

✓

Answer

Correct option: C.
shows a positive deviation from Raoult's law
c
A solution of acetone in ethanol shows a positive deviation from Raoults' law due to miscibility of these two liquids with difference of polarity and length of hydrocarbon chain.
