with the help of valence bond theory, explain as to why (cof6)power3-

1.	with the help of valence bond theory, explain as to why (cof6)power3- is paramagnetic, whereas (co(nh3)6)power3+ is diamagnetic. (atomic number of co=27)
Answer» CoF6 3- is paramagnetic because presence of unpaired ELECTRONS (F does not CAUSE pairing of d6 electrons) SP3D2 hybridisation Co(NH3)6 3+ diamagnetic because presence of PAIRED electrons. d2sp3 hybridisation (NH3 cause pairing of d6 electrons)

Answer»

CoF6 3- is paramagnetic because presence of unpaired ELECTRONS (F does not CAUSE pairing of d6 electrons)

SP3D2 hybridisation

Co(NH3)6 3+ diamagnetic because presence of PAIRED electrons.

d2sp3 hybridisation (NH3 cause pairing of d6 electrons)
