Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

van der Waals strain is strain resulting from van der Waals repulsion when two substituents in a molecule approach each other with a distance less than the sum of their van der Waals radii. Van der Waals strain is also called van der Waals repulsion and is related to steric hindrance.

what's the difference between internuclear and vanderwalss
![eduncle-logo-app]()
internuclear distance is distance between two nucleus...but when we talking about noble gas elements then radii is generally expresses in vanderwaals radii
