QNEET-2022-Ch-369: NEET 2022 Chemistry - Class 11 NEET-2022-Ch-369 Solution: Identify the incorrect statement from the following. All the…

Identify the incorrect statement from the following. All the five 5d orbitals are different in size when compared to the respective 4d orbitals. All the five 4d orbitals have shapes similar to the respective 3d orbitals. In an atom all the five 3d orbitals are equal in energy in free state. The shapes of

d_{xy} d_{yz}

and

d_{zx}

orbitals are similar to each other; and

d_{x^2-y^2}

and

d_{z^2}

are similar to each other.

Multiple Choice Options

A All the five 5d orbitals are different in size when compared to the respective 4d orbitals.
B All the five 4d orbitals have shapes similar to the respective 3d orbitals.
C In an atom, all the five 3d orbitals are equal in energy in free state.
D The shapes of d xy , d yz and d zx orbitals are similar to each other; and d x 2 $-$ _ y 2 and d z 2 are similar to each other.

Step-by-Step Verified Solution

_ In an atom, all the five 3d orbitals are equal in energy in free state i.e., degenerate. _ The shape of d x 2 _ y 2 is different then shape of d z 2 _ 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. _ Shape of orbitals depends on azimuthal quantum number 'I' therefore shapes of 4d orbitals are similar to the respective 3d orbitals.
