The oxide of potassium that does not exist is
- A \(\mathrm{K}_{2} \mathrm{O}\)
- B \(\mathrm{KO}_{2}\)
- C \(\mathrm{K}_{2} \mathrm{O}_{2}\)
- D \(\mathrm{K}_{2} \mathrm{O}_{3}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{K}_{2} \mathrm{O}_{3}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{K}_{2} \mathrm{O}_{2}\) may exists.
\(\mathrm{K}_{2} \mathrm{O}\) exists.
\(\mathrm{KO}_{2}\) also exists.
But, \(\mathrm{K}_{2} \mathrm{O}_{3}\) can not exist as \(\mathrm{O}_{3}^{2-}\) is not a stable entity.
