A liquid mixture contains 30% o-xylene, 60% p-xylene and 10%. m-xylene (all percentages in w/w). Which of the following statements would be true in respect of this mixture ?
Correct answer: E. The mixture exhibits an azeotrope at 101.3 kPa
- A. The mixture contain optical isomers
- B. The composition of the mixture, in percent by volume is: o-xylene 30, p-xylene 60. and mxylene
- C. 10
- D. The composition of the mixture in mole percent is: o-xylene 30, p-xylene 60 and m-xyoene 10
- E. The mixture exhibits an azeotrope at 101.3 kPa
Explanation
The stated weight percentages cannot also be the volume or mole percentages because the three xylene isomers have different molecular and density data. The listed true statement is the azeotropic behaviour of this mixture at atmospheric pressure; xylene isomers are not optical isomers.
