Question

Draw all of the possible isomers and provide the proper name for the following formula

[Co(NH₃)₃Cl₃]

Answer 1

17 * Here the given compound is - 2 [co (Nits) do This is an Mazba type of compo- und Here, M = Centroal metal atom - co a and b are two diffe. rent ligands for this type of compound there are two isomers possible i One in which three similar ligands are all adjacent at one face of the octahedron. L This type of isomen is called facial isomer NH3 Nts ... NH3 cu a Facial isomer

is Another one in which the throce similar ligands tend to occupy a positions such that two are in trans to each other This type of isomer is I called meridional a isomer menidional isomer So there are two isomers of Co (NH3)₂ elz] NH3 HB --INH3 z tů - - - - teta > 1) H₂N- ca "NH₂ facial isomer meridional isomer * Here we write the ligands name first with their alphabetical onder and then the metal with their oxi- dation states. So, the name of the

given compound troiamminetrichlorocobalt (111)
