MCQ
Identify the incorrect statement from the following.
  • A
    All the five $4 d$ orbitals have shapes similar to the respective $3 d$ orbitals.
  • B
    In an atom, all the five $3 d$ orbitals are equal in energy in free state.
  • The shapes of $d_{x y y^{\prime}} d_{y z}$, and $d_{z x}$ orbitals are similar to each other; and $d_{x} 2-y^{2}$ and $d_{z} 2$ are similar to each other.
  • D
    All the five $5 d$ orbitals are different in size when compared to the respective $4 d$ orbitals.

Answer
