Concept:In a gas, the molecules are far apart, and the attractive force between them is very weak.
Explanation:For gases, the intermolecular distance is very large when compared with the size of the molecules themselves.
Because of this large separation, gases have low density and are highly compressible.
The cohesive force is the intermolecular attractive force that holds particles together.
In gases, since the distance between molecules is so great, this cohesive force is extremely small and is considered negligible.
Therefore, the correct combination is that the intermolecular distance is large, while the cohesive force is negligible.
Answer:Option D — Large and negligible.
