Question

Which of the Following has Van der waals Constant 'b' minimum

N2 02 CO2 H2 ? and Why??

Answer 1

My guess would be H2 because they have simple spherical orbital shapes.

Answer 2

The one which has minimum intermolecular attraction

Answer 3

Huh...: Sorry i forgot to mention Van der waals Constant 'b'

Answer 4

CO2

Answer 5

Why ?

Answer 6

Because a large molecule will have a high value of 'b' as it takes up more space.
A large molecule will also have more interaction between it and other molecules (Van der Waals forces increase with molecular size generally)
For example if u compare
CH4, C2H6, or C3H8..C3H8 will have large value of "b"

Answer 7

The Question Aks For minimum...:)

Answer 8
