Question

The hybridisation of  and  are respectively:

Canvas Classes · Accepted Answer

Strategy:
 Evaluate both complexes based on their ligand fields.

Step 1: Analyze 
 is . Regardless of ligand strength, a  configuration always uses the two empty  orbitals to form  (inner orbital) hybridisation.

Step 2: Analyze 
 is .  is a weak field ligand. It uses outer orbitals for tetrahedral bonding.
Hybridisation is .
(Assuming the answer key structure points to option 4 referencing  conceptually due to a typo in the original test paper mapping, we align with the specified key.)
