Question

When potassium is reacted with water, which compound $(S)$ is are formed preferentially?

• A. $K_2O $
• B. $KO_2 $
• C. Both $K_2O $ and $KO_2$
• D. $K_2O_2$

Answer 1

The Correct Option is B

Due to large size of Potassium $(K)$ atom, it preferentially accomodate and form the bonds with two small oxygen atoms to give $KO _{2}$.

Hence, $KO _{2}$ is the preferential product when potassium react with water.
