Answer to Question #183188 in Inorganic Chemistry for Mbalenhle

Question

Answer the following questions for

Ammine chloro bisethylenediammine cobalt(III) sulphate

a.formula

b.the coordination number

c.the possible geometry of the coordination compound

d.the correct hybridization for the metal ion,based on the valence bond theory

e.the magnetic behaviour of the central metal ion

Answer 1

Formula

CO(NH₃)Cl₃(C₃₈H₇₆N₂O₂)2

Coordination number

8

Possible geometric isomers

designated facial and meridional

Hybridization

 H=12

(V+M−I)

H=12(V+M−I) where V

V is number of valence electron, M

M is number of single bonds and I

I is charge on the atom. Here if H=2

H=2 then it is sp

sp , H=3

H=3 then sp

2

sp2 and so on.

For CO(NH₃)Cl3

[(CO(NH₃₎X4], here V=10

V=10, M=4

M=4 and I=0

I=0, so H=7

H=7 hence sp³d³

sp³d³.

Magnetic behavior

Upon pairing it has one unpaired electron that makes it paramagnetic complex.
