Experiment 6: Bonding and properties
Date: June 18th 2019
Title: Bonding and properties
Purpose: To study the infrared Spectra and physical properties of molecules to determine what
kinds of intra-molecular bonds are present within the molecules and what kinds of inter-
molecular bonds are present between the molecules.
Procedure and results:
Solubility test:
1. Add KCl (ionic substances) into water in a test tube.
2. KCl is soluble in water because it dissolves in water.
3. Next add pentane into a different test tube filled with water.
4. A layer can be seen on top of the water. Hence, it’s non soluble.
- Do the same to copper chloride (CuCl) and you can see that it doesn’t dissolve.
- Add ethyl alcohol and butyl alcohol into water in separate test tubes and you can see that
it doesn’t dissolve in water. Butyl alcohol is partially soluble.
- Mix pentane and CuCl and you can see that CuCl dissolves in pentane.
- Iodine is soluble in pentane. Both like polar substances dissolve in each other.
Distillation method (18:00)
- To determine the boiling point and purify the substance
- The air is getting warmer and vapor is produced because of the heat produced.
- Goal is to measure the tertia butyl alcohol
- When the alchol fills the catch flask, that’s when it is distilled
- The boiling point: 81.4C
Do the same for the rest and measure their boiling point:
1. Ethanol: 76.4C
2. N-butyl alcohol: 115.3C
3. Acetic acid: 116.2C
4. Pentane: 34.8C
5. N- propyl chloride: 46.3C
