Question

Paramagnetic octahedral complex, [CoF6]3- uses outer orbital (4d) in hybridisation (sp3d2). It is thus called

1 point

(a) outer orbital complex

(b) high spin complex

(c) spin free complex

d) (a), (b), (c) all are correct​

Answer 1

Answer:

(d) option is correct

Explanation:

sp3d2 hybridization means it is outer orbital complex as well as high spin

free spin means having unpaired electron in it that is paramagnetic behavior

when we write oxidation number of Co this is here 3+

and electronic configuration of Co3+ is (Ar) 3d6

hence 4 unpaired electron

hope this will be helpful
