Which one of the following non-covalent interactions between two non-b...
Van der Wall Interactions, also known as London forces are the weakest noncovalent interactions that can occur between two non-bonded atoms A and B. In absence of any other force, A and B atoms, while approaching each other tend to repel rather than attract one another. The distance is called van der wall contact distance. These are found to be very sensitive towards the distance. The attraction between two uncharged atoms A and B are inversely proportional to r6 (r= radius of atom), whereas repulsion between two atoms is more sensitive to distance as it is inversely proportional to r12. The repulsion takes place due to both atoms’ electron clouds hindering them from approaching each other closely.

Understanding Non-Covalent Interactions
Non-covalent interactions play a critical role in molecular interactions, particularly in biological systems. The sensitivity of these interactions to distance varies depending on the type of forces involved.
Types of Interactions
- **Permanent Dipoles and Hydrogen Bonding**: In this case, the interaction is strong but relies on the specific orientation and distance. However, hydrogen bonds have a relatively moderate distance sensitivity.
- **Salt Bridges**: Fully ionized atoms (like charged residues in proteins) exhibit strong electrostatic interactions. This interaction is sensitive to distance but also to the dielectric environment, making it less sensitive than other interactions at short distances due to screening effects.
- **Uncharged Repulsive Interactions**: When two uncharged atoms are close, they experience repulsion due to electron cloud overlap. This repulsion increases sharply as distance decreases, making it very sensitive to changes in distance.
- **Uncharged Attractive Interactions**: These interactions, like London dispersion forces, become significant at short distances but decrease rapidly with increasing separation.
Why Option C is the Most Sensitive
The interaction between uncharged atoms that repel each other (Option C) is exceedingly sensitive to distance because:
- **Rapid Increase in Repulsion**: As the distance decreases, the overlap of electron clouds escalates, leading to a sharp increase in repulsive forces.
- **Short-range Interaction**: Repulsive forces are strong at very short ranges, meaning even slight changes in distance can lead to substantial changes in energy.
- **Greater Impact on Stability**: The stability of non-covalent complexes is significantly affected by these repulsive interactions, making them critical to molecular behavior.
In summary, the repulsive forces between non-bonded, uncharged atoms (Option C) are the most sensitive to distance changes, demonstrating a pronounced impact on molecular interactions.
