Question

Sp3d2 are all the orbitals having same size

• A. True
• B. False

Answer 1

Answer: (A)

True

Answer 2

The statement "Sp3d2 are all the orbitals having same size" refers to the characteristics of hybrid orbitals.

1. Hybridization: Sp3d2 hybridization involves the mixing of one s atomic orbital, three p atomic orbitals ($p_x, p_y, p_z$), and two d atomic orbitals ($d_{z^2}, d_{x^2-y^2}$) from the central atom.

2. Formation of Hybrid Orbitals: This mixing results in the formation of six new hybrid orbitals, known as sp3d2 hybrid orbitals.

3. Properties of Hybrid Orbitals:

   • Number: The number of hybrid orbitals formed is equal to the number of atomic orbitals that participate in hybridization (1 s + 3 p + 2 d = 6 sp3d2 orbitals).
   • Equivalence: All hybrid orbitals formed from a specific hybridization scheme (like sp3d2) are equivalent in energy, shape, and size. They are degenerate.
   • Orientation: These six sp3d2 hybrid orbitals are directed towards the corners of an octahedron, minimizing electron-electron repulsion and giving rise to an octahedral geometry.

Since all the sp3d2 hybrid orbitals are equivalent in all respects, including size, the given statement is correct.
