The correct IUPAC name of Mn3​(CO)12​ is:
  • A
    Mangesedodecylcarbonyl(0)
  • B
    Dodecacarbonylmanganate(0)
  • C
    Dodecacarbonylmanganic(II)
  • D
    Dodecacarbonyltrimanganese(0)

Answer

  1. Dodecacarbonyltrimanganese(0)

Explanation:

The correct IUPAC name of Mn3​(CO)12​ is dodecacarbonyltrimanganese(0). The central metal atom is a cobalt atom in zero oxidation state. The oxidation state is written in parenthesis.

Three such Mn atoms are present. Hence, the prefix tri is used. 12 carbonyl groups are present. Hence, the prefix dodeca is used.
