JEE Mains · Chemistry · STD 11 - 4. Chemical bonding and molecular structure
Number of paramagnetic oxides among the following given oxides is ..... . \(\mathrm{Li}_{2} \mathrm{O}, \mathrm{CaO}, \mathrm{Na}_{2} \mathrm{O}_{2}, \mathrm{KO}_{2}, \mathrm{MgO}\) and \(\mathrm{K}_{2} \mathrm{O}\)
- A \(1\)
- B \(2\)
- C \(3\)
- D \(0\)
Answer & Solution
Correct Answer
(A) \(1\)
Step-by-step Solution
Detailed explanation
\(\mathrm{Li}_{2} \mathrm{O} \quad \Rightarrow 2 \mathrm{Li}^{+}\quad\mathrm{O}^{2-}\) \(\mathrm{MgO} \Rightarrow \mathrm{Mg}^{2+}\quad \mathrm{O}^{2-}\) \(\mathrm{CaO} \quad \Rightarrow \mathrm{Ca}^{2+} \quad \mathrm{O}^{2-}\)…
