1. What is the Pauli exclusion principle
2. Specificity and selectivity are important concepts to understand in terms of chemical binding. Define specificity and selectivity? How do they differ? For a drug which is preferred, specificity or selectivity and why?
3. Are precipitation reactions used in diagnostics? Explain and give an example
4. Diffusion refers to the ability of molecules to move from a higher to lower concentration. Would you predict molecules to diffuse faster or slower than larger sized one? Explain.
