NEETChemistryStructure of AtomMCQ+4 / −1
Identify the incorrect statement from the following.
- AAll the five 5d orbitals are different in size when compared to the respective 4d orbitals.
- BAll the five 4d orbitals have shapes similar to the respective 3d orbitals.
- CIn an atom, all the five 3d orbitals are equal in energy in free state.
- DThe shapes of dxy, dyz and dzx orbitals are similar to each other; and dx2 y2 and dz2 are similar to each other.

Correct answer: D
$\bullet$ In an atom, all the five 3d orbitals are equal in energy in free state i.e., degenerate.
$\bullet$ The shape of dx2 $-$ y2 is different then shape of dz2
$\bullet$ The size of orbital depends on principal quantum number 'n' therefore all the five 3d orbitals are different in size when compared to the respective 4d orbitals.
$\bullet$ Shape of orbitals depends on azimuthal quantum number 'I' therefore shapes of 4d orbitals are similar to the respective 3d orbitals.
