Among the following, the incorrect statement is
- A Cesium forms superoxide
- B Sodium peroxide is paramagnetic
- C Lithium chloride is deliquescent
- D White metal is an alloy of lithium and lead
Answer & Solution
Correct Answer
(B) Sodium peroxide is paramagnetic
Step-by-step Solution
Detailed explanation
Sodium peroxide has peroxide ion \(\mathrm{O}_2^{2-}\) that has a total of 18 electrons and is diamagnetic. The superoxide ion \(\mathrm{O}_2^{-}\)is paramagnetic.
