Hello champions! Welcome back  to my virtual lab. The 1st video, made by KMPk's lecturer. Its a demo video. I'm sure you will have better understanding regarding to the procedure after watching this video.



Next video is from KMP. Writing lab report will be much easier after watching this video.


Table of result

                                 Test
Hydrocarbon

Bromine Test

Oxidation test with alkaline KMnO4

Under sunlight

In the dark

Cyclohexane

The reddish brown colour of bromine decolourised

The reddish brown colour of bromine remains unchanged

The purple colour of KMnO4 remained unchanged

Cyclohexene

The reddish brown colour of bromine decolourised

The reddish brown colour of bromine decolourised

The purple colour of KMnO4 decolourised and brown precipitate form

Toluene

The reddish brown colour of bromine decolourised

The reddish brown colour of bromine remains unchanged

The purple colour of KMnO4 decolourised


Tips to write observations:
- your observation must include colour before and after reaction.
-example:
(i) correct observation: The reddish brown colour of bromine remains unchanged
(ii) incorrect observation: colour of bromine remains unchanged (because it is incomplete)

Please refer this video for mechanism halogenation of cyclohexane.



 See you again at next experiment.
