Question

Write IUPAC names $[Co(NH_{3} )_{5}Cl]SO_{4}$.

Answer 1

Answer:

Explanation:

This is a positive complex.

According to IUPAC naming,in positive complexes,first we name ligands alphabetically,then name the central metal(specifying the oxidation state of metal) and then the anion part.

Here, central metal is Co,ligands are NH3,Cl and (SO4)2- is the anionic part.

Oxidation state of cobalt here is +3(since net charge on coordination sphere is +2,and Cl is -1)

Alphabetically,NH3 comes first.So name is Triamminechlorocobalt(III) sulphate.
