Question

Conclusion / Inference:
a. Potassium permanganate oxidizes ethanol to ............. As potassium permanganate is consumed
in this reaction its ............. colour vanishes.
b. Iodine is consumed due to its addition to fatty acid. Therefore the coloured solution becomes
colourless. But when the same procedure is followed for vanaspati ghee, a similar colour change
is not observed. As vanapati ghee is saturated hydrocarbon the ............ reaction does not
occur there.
​

Answer 1

Answer:  a-Ethanoic acid, purple

                b-bromination/hydrogemation

Explanation:

For A ethanol under goes oxidation reaction alk KMno4 is the oxidising agent it oxidises ethanol to ethanoic acid. During this reaction alk Kmno4 undergoes decolourisation , it losses its purple colour..

For B Fatty acid is an Unsaturated Hydrocarbon so so it under goes Hydrogenation so iodine decolourises . Vanaspathi Ghee is Saturated so it does not undergo Hydrogenation so iodine does not decolourise...

B's explanation is a bit cracky...
