I am confused with gas chromatography. The question I am being asked is why did we use column B (silicone oil) for separating 1-butene, trans-2-butene, and cis-2-butene from each other in a GC. I have answered all the other questions but I'm completely stuck on this one; can anyone help please?
Homework Answers
Silicone oil is very good for heating because it gives homogeneous heating. Homogeneous heating is necessary for ionisation of molecules according to their boiling points. In GC, silicone oil is used as a solvent also. Generally we use silicone oil and fluoro-silicone oil for better separation.
Now here, the molecules have different boiling points. And they differently act with silicone oil.

I need help figuring out what kinds of collisions we did in lab and what they should hypothetically be. All parts use 2 Vernier Encoder Standard Cart, unless stated otherwise. Cart I is always pushed towards Cart II's specified surface of collision and motion sensor is used to record on both sides. "Classify each collision as elastic, inelastic, perfectly inelastic, or explosive." Part I - Cart I: VES cart. Cart II: Vernier Dynamics Cart with plunger. The no velcro/magnetic end...
