MCQ
Which one of the following complexes is paramagnetic
  • A
    ${[Co{(F)_6}]^{3 + }}$
  • B
    ${[Co{({H_2}O)_6}]^{3 + }}$
  • C
    $[Co{F_3}{({H_2}O)_3}]$
  • All of these

Answer

Correct option: D.
All of these
d
(d) As all the ligands are weak so they do to induce pairing of electrons so they show paramagnetism.
