A graph of vapour pressure and temperature for three different liquids X , Y and Z is shown below: The following inferences are made: A X has higher intermolecular interactions compared to Y . B X has lower intermolecular interactions compared to Y . C Z has lower intermolecular interactions compared to Y . The correct inferences is/are:
Options
- AA and C
- BA
- CB
- DC
Correct answer
C. B
Step-by-step solution
At a particular temperature as intermolecular force of attraction increases vapour pressure decreases. order of intermolecular interactions Z>Y>X
