Answer 1

Answer:

Di-chloro-bis-( ethylenediamine) cobalt(|||) nitrate.

Answer 2

IUPAC name of $[CoCl_2(en)_2]NO_3$ is dichloro bis(ethylidenediammine)cobalt(III) nitrate.

• The given complex is $[CoCl_2(en)_2]NO_3$.
• Let the oxidation state of Co be x.
• So, we can write-
• x-2-1=0
• x=+3
• Hence the oxidation state of Co is +3.
• The ligands 'en' is bidentate so, we should write 'bis(ethylidenediammine).'
• Co will write as cobalt.
• Cl will write as dichloro.
• Applying all the rules the name of the above complex is as follows-
• dichloro bis(ethylidenediammine)cobalt(III) nitrate.
