The oxidation of hexan-1-ol with acidified potassium dichromate results in the formation of ________.
Potassium manganate $\left(\mathrm{K}_{2} \mathrm{Mn} \mathrm{O}_{4}\right)$ is formed when (1) Chlorine is passed through aqueous $\mathrm{KMnO}_{4}$ solution (2) Manganese dioxide is fused with potassium hydroxide in air (3) Formaldehyde reacts with potassium (4) potassium permanganate reacts with $\mathrm{H}_{2} \mathrm{SO}_{4}$

Multiple Correct Answers Type
Potassium permanganate, $\mathrm{KMnO}_{4},$ is one of the most widely used oxidizing agents. Balance each of the following oxidation-reduction reactions of the permanganate ion in acidic solution by using the “half- reaction” method. $$ \begin{array}{l}{\text { a. } \mathrm{MnO}_{4}^{-}(a q)+\mathrm{C}_{2} \mathrm{O}_{4}^{2-}(a q) \rightarrow \mathrm{Mn}^{2+}(a q)+\mathrm{CO}_{2}(g)} \\ {\text { b. } \mathrm{MnO}_{4}^{-}(a q)+\mathrm{Fe}^{2+}(a q) \rightarrow \mathrm{Mn}^{2+}(a q)+\mathrm{Fe}^{3+}(a q)} \\ {\text { c. } \mathrm{MnO}_{4}^{-}(a q)+\mathrm{Cl}^{-}(a q) \rightarrow \mathrm{Mn}^{2+}(a q)+\mathrm{Cl}_{2}(g)}\end{array} $$
