MCQ
A completely filled $d$-orbital $({d^{10}})$
- ✓Spherically symmetrical
- BHas octahedral symmetry
- CHas tetrahedral symmetry
- DDepends on the atom
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.
