Worked practice questions

The correct IUPAC name of [NiCl₂(PPh₃)₂] is

Dichloridonickel(II) triphenylphosphine
Dichloridobis(triphenylphosphine)nickel(II)
Bis(triphenylphosphine)nickeldichloride
Nickel(II) chloride phosphine complex

Show answer and solution

Correct answer: B. Dichloridobis(triphenylphosphine)nickel(II)

1. Ligands are alphabetised: chloro (or chlorido) comes before triphenylphosphine. 2. The prefix "bis" (not di) is used for ligand names already carrying a numeric prefix. 3. Oxidation state of Ni is +2, indicated in Roman numerals. 4. So syllabus names it dichloridobis(triphenylphosphine)nickel(II). _Source: syllabus Chemistry, Unit 5 "Coordination Compounds", §5.3.2(iv)_
