The paramagnetic species is

Options

  1. AKO ₂
  2. BSiO ₂
  3. CTiO ₂
  4. DBaO ₂ .

Correct answer

A. KO ₂

Step-by-step solution

KO ₂ is a superoxide of potassium containing superoxide ion, O ²⁻ which has a three electron bond. Thus this ion can be represented as The presence of one unpaired electron in three electron bond makes this ion paramagnetic.
