The bond order values of anions of sodium peroxide and potassium super oxide are respectively.
Options
- A1,1.5
- B1,0.5
- C0.5,1
- D2,0.5
Correct answer
A. 1,1.5
Step-by-step solution
The peroxide ion in sodium peroxide is O ₂²⁻ has total of 18 electrons. Electronic configuration of O ₂²⁻ is 1 s^2, ^* 1 s^2, 2 s^2, ^* 2 s^2, 2 p_z^2, 2 p_x^2 2 p_y^2 , ^* 2 p_x^2 ^* 2 p_y^2 Bond order aligned & = 1 2 [ array l No. of bonding - No. of non-bonding orbital electrons orbital electrons array ] & = 1 2 [10-8]=1 aligned The superoxide in potassium superoxide is O ₂⁻ has total of 17 electrons. Electronic configuration of O ₂⁻ is 1 s^2, ^* 1 s^2, 2 s^2, ^* 2 s^2, 2 p_z^2, 2 p_x^2 2 p_y^2 , ^* 2 p_x^2 ^* 2
