The correct statement about  and  is:

Canvas Classes · Accepted Answer

Strategy:
 Use Valence Bond Theory (VBT) to determine hybridisation and magnetic properties based on ligand strength and oxidation state.

Step 1: Analyze 
 is . Since  is a strong field ligand,  electrons pair up in the  orbital to yield a  configuration.
Hybridisation:  (Tetrahedral).
Unpaired electrons = 0  Diamagnetic.

Step 2: Analyze 
 is .  is a strong field ligand, forcing pairing of the two unpaired d-electrons. This empties one  orbital.
Hybridisation:  (Square planar).
Unpaired electr
