Solutions Question 308
Question: A binary liquid solution is prepared by mixing n-heptane and ethanol. Which one of the following statements is correct regarding the behaviour of the solution'
Options:
A) The solution is non-ideal, showing -ve deviation from Raoult’s Law.
B) The solution is non-ideal, showing +ve deviation from Raoult’s Law.
C) n-heptane shows +ve deviation while ethanol shows -ve deviation from Raoult’s Law.
D) The solution formed is an ideal solution.
Show Answer
Answer:
Correct Answer: B
Solution:
For this solution intermolecular interactions between heptane and ethanol are weaker than heptane -heptane and ethanol -ethanol interactions hence the solution of heptane and-ethanol is non-ideal and shows positive deviation from Raoult’s law.
