Question

I will give 5 stars if you can answer any one of the following questions well. But i would really appreciate if you were awesome enough to attempt the rest as long as you have an idea :)

1) Explain why 1-butanol and butanone have such different boiling points
2) Explain which distilation method (fractional or simple) would be most appropriate to seperate hexanes and dichloromethane.
3) If glass beads in the lab were replaced by a material with less surface area, will liquid seperation be better or worse? Why?
4) Why should the recieveing flask be submersed under an ice bath when collecting isopropanol or acetone?

*****Please explain in full (i.e more than 1 sentance) Thanks

Explanation / Answer

1.)1-butanol's structure is more straight that 2-butanol so that the molecules can interact each other better, which means stronger van der Waals force among molecules. To disociate each molecule from the body of liquid, which also known as boiling, more energy will be required. The strongest intermolecular force that is happening in this molecule is hydrogen bonding, the T-butyl group will do a better job of blocking off one side of the -OH group, making it a little bit harder to make a hydrogen bond (the net result being the T-Butanol has a lower boiling point).
