Question

The prefix di is used twice in the naming of [NiCl2(PPh3)2].

(a) True

(b) False

This question was posed to me during an internship interview.

I want to ask this question from Nomenclature of Coordination Compounds in section Coordination Compounds of Chemistry – Class 12

Answer 1

The correct answer is (b) False

The best I can explain: The prefix di is used only once for chlorido. For the PPh3 ligand, the prefix bis is used instead, as PPh3 (triphenylphosphine) already includes a numerical prefix in its name.
