Match List-I (Complex) with List-II (Hybridisation & Magnetic characters):

(A) , (B) , (C) , (D)

(I)  & diamagnetic, (II)  & paramagnetic, (III)  & diamagnetic, (IV)  & paramagnetic

Canvas Classes · Accepted Answer

Strategy:
 Identify the oxidation state, coordination number, and ligand field strength to deduce the hybridization algorithm and count unpaired electrons for magnetic properties.

Step 1: Analyze each complex
- (A) : Tetrahedral .  with weak field . Outer  hybridization. Has 5 unpaired electrons  Paramagnetic. (Matches IV).
- (B) : Octahedral  (). Weak field  forces high-spin. No empty inner d-orbitals exist, mandating outer  hybridization. Has 5 unpaired electrons  Paramagnetic. (Matches II).
