The geometry and the number of unpaired electrons in tetrakis (1 - norbornyl)Co 
respectively, are:
respectively, are:(a)tetrahedral and five
(b)square planar and three
(c)tetrahedral and one
(d)square planar and one
Answer
Answer: C ✓ checked by 4AB · confidence high
Explanation
Tetrakis(1-norbornyl)cobalt is Co(IV), d⁵, tetrahedral; the very strong σ-donor alkyls make it low-spin (e⁴t₂¹), so it has one unpaired electron.
