Hydrates: Naming Compounds with Water Built In
Some ionic compounds don't just sit in crystal form on their own — they trap a fixed number of water molecules inside their crystal lattice. These are called hydrates, and today we'll learn how IUPAC-

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…

– the E nomenclature Most cars in the United States can run on ‘E10’ – gasoline containing 10% ethanol by volume. In corn-producing regions of the USA, higher proportions of ethanol are common: E85 is widely a vailable. In Brazil, some vehicles run on 100% ethanol (E100), but an ethanol content of at least 18% (E18) is mandatory for all gasoline vehicles. In Sweden, flex-fuel v…
