Question

What would be observed on adding 50% solution of alkaline potassium permanganate drop by drop to some warm ethanol taken in a test tube? Write the name of the compound formed during chemical reaction.

Answer 1

Step 1:

In an organic reaction, a reagent reacts with a reactant molecule to produce an intermediate which is converted into final products.

When the solution of alkaline Potassium permanganate $\left({\mathrm{KMnO}}_4\right)$ is added dropwise to warm Ethanol $\left({\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}\right)$, then a chemical reaction takes place and oxidation of Ethanol gives to Ethanoic acid $\left({\mathrm{CH}}_3\mathrm{COOH}\right)$.

Step 2: Chemical reaction

The chemical reaction of Ethanol with Potassium permanganate $\left({\mathrm{KMnO}}_4\right)$ is given as:

$$\begin{gathered} {\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}+\mathrm{alk}.{\mathrm{KMnO}}_4\to {\mathrm{CH}}_3\mathrm{COOH} \\ \mathrm{Ethanol}\mathrm{Ethanoic}\mathrm{acid} \end{gathered}$$

Hence, the name of the compound is Ethanoic acid $\left({\mathrm{CH}}_3\mathrm{COOH}\right)$.
