MCQ
A completely filled $d$-orbital $({d^{10}})$
  • ✓
    Spherically symmetrical
  • B
    Has octahedral symmetry
  • C
    Has tetrahedral symmetry
  • D
    Depends on the atom
✓

Answer

Correct option: A.
Spherically symmetrical
a
$d ^{10}:-$

Often tetrahedral complexes limited to form $4$ additional bonds $(8$ additional electrons) by the $18$-electron ceiling. Often colorless due to the lack of $d$ to $d$ transitions.

Tetrahedral geometry is common for complexes where the metal has $d ^0$ or $d ^{10}$ electron configuration.
