Question

iupac name of [Cu(H2O)2(NH3)5]Cl2​

Answer 1

Answer:

Copper(II)pentaaminediaquacloride.

Explanation:

• Name the cation first.
• Look at anion to determine valency of the d-block cation.
• Name the lig and as per alphabetical order regarless of numbers.
• Aqua is used for water and amine for NH3 group.
• Name the anion.

Answer 2

IUPAC name of the given compound is Pentaamminediaquacopper(II) chloride

• The given compound is a type of coordination compound in which the complex has a positive charge, that is, it is a positive complex coordination compound.
• In such a compound the name of the central atom will remain the same and we will first name the complex followed by the central metal atom along with its oxidation state and the anion. (Left to right)
• Name of H₂O - aqua
• Name of NH₃  - ammine
• The oxidation state of copper will be 2 (H₂O and  NH₃ are neutral ligands and do not have any charge, it is given chloride has two atoms with a total charge of -2, thus to neutralize copper has an o.s. of +2)

• Name of  [Cu(H₂O)₂(NH₃)₅]Cl₂ - Pentaamminediaquacopper(II) chloride
