Problem- 1) Which hydrocarbon (n-hexane or cyclohexene) contains a multiple bond? Explain
2) Do the experimental results confirm the reactivity of primary and secondary alcohols with KMnO4 and the lack of reactivity of tertiary alcohols in KMnO4? Explain. (the lab is called Organic Compounds: Functional Groups)
3) A student added three mL of KMnO4 instead of the three drops of 0.1 M KMnO4.How will these affect this results? What do you think will be observed in each solution?
If possible just a brief explanation how you got the answer?
