Question

Alkaline Potassium permanganate and Potassium dichromate convert alcohols into carboxylic acids by adding oxygen.

• A. True
• B. False

Answer 1

The correct option is A True

The substances which are capable of adding oxygen to other substances are called Oxidizing agents. Alkaline $KMn{O}_4$ and acidified $K_{2}C{r}_2{O}_7$ convert alcohols to carboxylic acids by adding oxygen. This is because, per molecule of Alkaline $KMn{O}_4$ or acidified $K_{2}C{r}_2{O}_7$ we get more number of oxygen.
$KMn{O}_4$ dissociates into $K^{+}$ and ${Mn{O}_4}^{-}$ while $K_{2}C{r}_2{O}_7$ dissociates into $2K^{+}$ and ${C{r}_2{O}_7}^{2-}$.
