Microscale Organic Chemistry Lab Questions

1. Identify four moisture-protected reaction apparatus. I have identified 2 apparatus (Moisture-protected Claisen head with 3 or 5mL conical vial, arranged for syringe addition and magnetic stirring, and Moisture-protected water-jacketed condenser with 3 or 5mL conical vial, arranged for heating and magnet stirring). I may be making this harder than it should be and my question is: Does the Claisen head with 3 or 5mL conical vial constitute two apparatus, as well as the moisture-protected water-jacketed condenser with 3 or 5mL as two apparatus? If so, this would give me the four apparatus requested.

2. What is the basis for distillation techniques used to separate two or more components? I may be way off base, but from what I understand, different distillation techniques are used when substances have different boiling points. Simple distillation techniques can be used where liquid is separated from a nonvolatile solute and the vapor phase consists of only one component. Am I correct in thinking that it needs to be fractional semimicroscale distillation with multiple theoretical plates for two or more components, or am I way off?

1. In question one you are missing one important thing. If this apparatus is for moisture-protected reaction there should be a guard tube. The guard tube should be at the receiver where you will obtain the distillate. And if you are planning a reaction just for refluxing there should be a guard tube at the upper end of the condenser. The guard tube is a simple apparatus which is filled with ...

Not appropriate for library submission..

here is my revisions please let me know if this is better, on problem 3 our professor said to ignore presenting data, we just need to do a flow chart but I'm still confused about what I'm missing or the corrected one is better, I didnt the unknowns part i did the knowns portion of lab, we were told what what we started with we had to determine it from melting points so if you could please tell me what I'm missing from that specific flow chart?!
