Question

Which of the following false for tetrahedral complexes?

• A. Low spin
• B. High spin
• C. d-d transition
• D. Coloured

Answer 1

Answer: (A)

Low spin

Answer 2

Tetrahedral complexes show $sp^3$ hybridisation, so low spin (pairing of electrons in the d-orbitals) is false for tetrahedral complexes.
Tetrahedral compIexes show $d-d$ transition due to high spin of $d$-orbitals.
Tetrahedral complexes are coloured due to the absence of symmetry and presence of unpaired electron in $d$-orbitals.
