Calculate the number of unpaired electrons in [ M n ( H 2 O ) 6 ] 2 + , Considering H 2 O as a weak field ligand ( At . No . of Mn = 25 )

Question

Calculate the number of unpaired electrons in [ M n ( H 2 O ) 6 ] 2 + , Considering H 2 O as a weak field ligand ( At . No . of Mn = 25 ), Two, Three, Four, Five

MARKS App · Accepted Answer

M n 25 → 3 d 5 4 s 2 M n 2 + → 3 d 5 In presence of weak ligand field, there will be no pairing of electrons. So, it will form a high spin complex. i.e. the number of unpaired electrons = 5.
