- Need explanation for: - Solutions - JEE Main
A binary liquid solution is prepared by mixing and
. Which one of the following statements is correct regarding the behaviour of the solution ?
- Option 1)
The solution formed is an ideal solution
- Option 2)
The solution is non-ideal, showing +Ve deviation from Raoult’s law
- Option 3)
The solution is non - ideal ,showing -Ve deviation from Raoult’s law
- Option 4)
shows +Ve deviation while
shows -Ve deviation from Raoult’s law.
Answers (1)
As we learnt in
Condition for positive deviation -
When A - A interactions and B - B interactions are stronger than A - B interactions.
e.g. Ethanol + water
- wherein
Between two n-hexane molecule the force interaction is Vander Waal and between two molecule ethanol the force of interaction is Hydrogen bond. Hence when both are mixed together their interaction are weaker than previous one so they shows positive deviation.
Correct option is 3.
Option 1)
The solution formed is an ideal solution
This is an incorrect option.
Option 2)
The solution is non-ideal, showing +Ve deviation from Raoult’s law
This is an incorrect option.
Option 3)
The solution is non - ideal ,showing -Ve deviation from Raoult’s law
This is an incorrect option.
Option 4)
shows +Ve deviation while
shows -Ve deviation from Raoult’s law.
This is an incorrect option.
