Introduction
Aromatic hydrocarbons have a significant organic compounds containing aromatic cycles only contains 6 carbon atoms.
The easiest aromatic hydrocarbon is benzene.
A simple aromatic hydrocarbon is benzene. It is chemical formula is C6H6. The benzene molecule is composed of 6 carbon atoms joined in a ring with 1 hydrogen atom attached to each.
The 6 benzene carbons make up a special cycle. 2 out of 4 carbon atom electrones every atom uses to bond with the ones next to it. The 3rd electrone all carbons use to bond with a hydrogen and the 4th to make up a ringlike system.
Task
Watch Video materials in link and acording to that, answer to questions.
https://www.youtube.com/watch?v=cSBbRgPX8zU
Process
- What is substantially different aromatic hydrocarbons of saturated and unsaturated hydrocarbons.
- How many double links are in benzene?
- Witch hydrocarbon molecule have one or more benzene rings?
- Why benzene molecul are problem to display?
- What is benzene molecular formula?
Definition questions:
- Xylole -
- Toluene -
- Naphtalene -
- Biphenyl -
- Ethylbenzene -
Evaluation
- Aromatic hydrocarbons link consists of benzene ring /s.
- Three
- Arēni
- Display the benzene molecule is problematic, because all C-C links are the same, but its not easy, not dubultsaitei link.
- C6H6
Definition questions:
- Xylole - solvent
- Toluene - paint, medicene, explosives
- Naphtalene - paint, solvent, processing fur
- Biphenyl - heat transfer agent
- Ethylbenzene - polysterene
Conclusion
If you answered more than five questions correctly, than you have successfully completed the aromatic hydrocarbons theme.
If you want know more you can look to the next topics of saturated and unsaturated hydrocarbons.
