Expert Answer
Observations:
When KMnO4 is added to
1)Ethane:
When KMNO4 is treated with ethane there is no reaction between ethane and KMNO4, the purple colour of KMnO4 has remained same.
2) Ethene:
When KMNO4 is treated with ethene, it oxidizes ethene to give ethane-1,2-diol (ethylene glycol).
The purple colour of KMNO4 changed to colourless after oxidation.
3) Ethyne:
i) Cold KMNO4 :
Ethyne reacts with cold KMnO4 to form formic acid.
ii) Hot KMNO4 :
Ethyne reacts with hot KMnO4 to form oxalic acid.
