Mircoscale 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. I'm 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?
