Which of the following is paramagnetic?
Options
- AO 2
- BCN -
- CCO
- DNO +
Correct answer
A. O 2
Step-by-step solution
MO electronic configuration of O 2 is σ 1 s 2 , σ 1 * s 2 , σ 2 s 2 , σ 2 * s 2 σ 2 p z 2 , π 2 p x 2 , π 2 p y 2 , π 2 * p y 1 , π 2 * p x 1 Due to presence of unpaired electron in ABMO π 2 * px & π 2 * py behaves paramagnetic.
