Question

how many unpaired electrons are present in d orbital of central metal ion in [Co(NH3)6]3+​

Answer 1

Answer:

0

Explanation:

It has 3 paired elctrons

Answer 2

Co = 27 = 1s2 ,2s2,2p6,3s2,3p6,3d7,4p2

d orbital contain 7 electrons

s orbital contain 2 electrons

p orbital remains empty

After removal of 3 electrons:

d orbital contain 6 electrons

s orbital become empty

P orbital will remain empty

After hybridization:

d orbital will contain 3 pair of electrons

Which shows that it is diamagnetic since it does not contain any unpaired electron

Hence no. of unpaired electron is 0.
