Verified step by step guidance

Understand that the Van der Waals constant 'b' represents the volume occupied by one mole of molecules in a gas. It is related to the size of the molecules; larger molecules have a larger 'b' value.

Consider the molecular size of each compound. Larger molecules or those with more atoms generally have a larger volume and thus a larger 'b' value.

Compare the molecular sizes: O2 is a diatomic molecule, CH3CH3 (ethane) is a small organic molecule, HBr is a diatomic molecule with a heavier atom, S8 is a large ring molecule, and Ne is a noble gas with a single atom.

Recognize that S8, being a large ring molecule with eight sulfur atoms, is significantly larger in size compared to the other molecules listed.

Conclude that S8 is expected to have the largest Van der Waals constant 'b' due to its large molecular size compared to the other gaseous compounds listed.
