- 1. Open EndedDistillation and Reflux: What is the purpose of carrying out a reflux?
- 2. Open EndedDistillation and Reflux: Reflux- which glassware are needed in its set-up? (picture
- 3. Open EndedDistillation and Reflux: Reflux- which glassware are needed in its set-up? (items)
- 4. Open EndedLLE: As the two liquids separate, the solute compounds will redistribute into either of the layers based on the solubilities of the respective compounds. The efficiency of this transfer is based on a partition coefficient (K) which is defined as,

- 7. Open EndedLLE: What is the theory behind separating a mixture using liquid-liquid extraction?
- 8. Open EndedDistillation and Reflux: What the purpose of carrying out a distillation?
- 9. Open EndedLLE: How does ionization of a given molecule affect its distribution between the organic and aqueous layer?
- 10. Open EndedDistillation and Reflux: Distillation- which glassware are needed in its set-up? (picture)
- 11. Open EndedRe-crystallization: Why is the solution allowed to cool down to room temp rather than placing it immediately in an ice bath?

- 15. Open EndedTLC: Can you calculate the Rf value of a given spot on a TLC plate?
- 16. Open EndedGC: What is the stationary and mobile phase in GC?
- 17. Open EndedIR: How/when can IR spectroscopy be useful in monitoring the progress of a given reaction?
- 18. Open EndedGC: Given a mixture of molecules (minor and major products and their BP), which one would you expect to have the higher retention time? and which one would you expect to have the larger surface area under the peak?

- 20. Open EndedRe-crystallization: What temperature should the extraction solvent be at and why?
- 21. Open EndedRotavap: What is the purpose of using a rotavap?
- 22. Open EndedDrying agents: What is the purpose of drying agents?
