Nomenclature – ternary compounds (II)

Nomenclature – Ternary Compounds (II)

In the previous lesson you met oxyanions – polyatomic ions made of an element bonded to several oxygen atoms, like SO₄²⁻ or NO₃⁻ – and learned that IUPAC gives these a consistent, unambiguous naming system so that chemists everywhere understand exactly which compound is meant (Talbot, p.172). This lesson builds on that by looking at what happens when an element forms more than one oxyanion, how we name the acids derived from these ions, and how we combine everything when a transition metal cation is also involved.

Recap: the basic –ate ending

As you saw before, the standard oxyanion name ends in **

S2: Models of bonding and structure 160 TOK What is the role of nomenclature and terminology in the chemical community? The role of IUPAC (International Union of Pure and Applied Chemistry) is interesting to consider in relation to theory of knowledge. One of the primary roles of IUPAC is to recommend: unambiguous, uniform, and consistent nomenclature and terminology for specif…

S3.2 Functional groups: classification of compounds 277 Nomenclature of organic compounds To clearly identify organic molecules, a systematic method of naming has been developed by IUPAC (the International Union of Pure and Applied Chemistry). In the IUPAC system of nomenclature, the names of organic molecules correlate with their structures and have three parts determined as s…

S2: Models of bonding and structure 118 Examples of compounds containing these ions are potassium oxide, K2O [2K+ O2−]; potassium nitride, K3N [3K+ N3−]; potassium cyanide, KCN [K+ CN−]; and potassium hydroxide, KOH [K+ OH−]. Ammonium chloride has the formula NH4Cl [NH4 + Cl−]. What are the names of the compounds with the formulas CoCl 2 and BaCl2? Answer Cobalt is a transition…
