Question

The paramagnatic property of the oxygen molecule due to the presence of unpaired electrons present in:

• A. $(\sigma 2p_x{)}^1$ and $({\sigma }^{\ast }2p_x{)}^1$
• B. $(\sigma 2p_x{)}^1$ and $(\pi 2p_y{)}^1$
• C. $({\pi }^{\ast }2p_y{)}^1$ and $({\pi }^{\ast }2p_x{)}^1$
• D. $({\pi }^{\ast }2p_y{)}^1$ and $(\pi 2p_y{)}^1$

Answer 1

The correct option is C $({\pi }^{\ast }2p_y{)}^1$ and $({\pi }^{\ast }2p_x{)}^1$

The paramagnetic property in oxygen came through unpaired electron which can be explained which can be explained by molecular orbital theory.
