The correct Answer is:
To determine the characteristics of `sp^3d` hybridization, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Hybridization**: Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals that can accommodate the bonding pairs of electrons in a molecule. 2. **Identifying the Orbitals Involved**: In `sp^3d` hybridization, one s orbital, three p orbitals, and one d orbital are mixed. This results in the formation of five hybrid orbitals. 3. **Calculating the Steric Number**: The steric number is defined as the number of atoms bonded to the central atom plus the number of lone pairs on the central atom. For `sp^3d`, the steric number is 5. 4. **Determining the Molecular Geometry**: A steric number of 5 corresponds to a trigonal bipyramidal geometry. This means that the arrangement of the atoms around the central atom forms a shape where three atoms are in a plane (equatorial) and two atoms are above and below this plane (axial). 5. **Conclusion**: Therefore, `sp^3d` hybridization is associated with a trigonal bipyramidal shape. ### Final Answer: `sp^3d` hybridization has a trigonal bipyramidal shape. ---

Assertion: Transition metal ion forming octahedral complexes undergo sp^(3)d^(2) or d^(2) sp^(3) hybridisation. Reason: Strong field ligands force the unpaired electrons of central metal ion to pair up causingg d^(2)sp^(3) hybridisation whereas weak field ligands do not affect electronic configuration of the metal ion undergoes in sp^(3)d^(2) hybridisation.
