Baeyer's reagent is:
Baeyer's Reagent is Alkaline $$KMnO_4$$ at $$0-5^oC$$ temperature. It is used to add cis-diols in Alkenes.
A solution of $$KMnO_{4}$$ on reduction yields either a colourless solution or a brown precipitate or a green solution depending on $$pH$$ of the solution. What different stages of the reduction do these represent and how are they carried out?
These questions consists of two statements each, printed as assertion and reason, while answering these questions you are required to choose any one of the following responses. Assertion : $$KMnO_4$$ is purple in colour due to charge transits Reason : There is no electron present in dentine's of manganese in $$MnO_4$$.
Heaviest atom among the following is:
The color of $$KMnO_4$$ is due to :
When $$MnO_2$$ is fused with KOH and $$O_2$$, what is the product formed and its colour?
The colour of $$KMnO_4$$ disappears when oxalic acid is added to its solution in an acidic medium. This can be explained as :
