What do you mean by Iupac system of nomenclature?
IUPAC nomenclature is based on naming a molecule’s longest chain of carbons connected by single bonds, whether in a continuous chain or in a ring. All deviations, either multiple bonds or atoms other than carbon and hydrogen, are indicated by prefixes or suffixes according to a specific set of priorities.

What is IUPAC example?
The IUPAC name is therefore: 2,5,5-trimethyl-2-hexene. In example (2) the longest chain incorporating both carbon atoms of the double bond has a length of five. There is a seven-carbon chain, but it contains only one of the double bond carbon atoms. Consequently, the root name of this compound will be pentene.
How do you write an Iupac name?
In summary, the name of the compound is written out with the substituents in alphabetical order followed by the base name (derived from the number of carbons in the parent chain). Commas are used between numbers and dashes are used between letters and numbers. There are no spaces in the name.
Does n mean moles?
n = m/M n is the amount of substance, in moles, mol. m is the mass of the substance, in grams, g. M is the molar mass of the substance (the mass of one mole of the substance) in g mol-1.
Which nomenclature is in use today?
The system of biological naming (or, nomenclature) that we use today was developed by Swedish botanist Carl Linnaeus (1707-1778). Portrait of Carl Linnaeus (Wikimedia Commons; public domain).
What is the purpose of nomenclature?
The primary function of chemical nomenclature is to ensure that a spoken or written chemical name leaves no ambiguity concerning which chemical compound the name refers to: each chemical name should refer to a single substance.
What is Iupac and its function?
The International Union of Pure and Applied Chemistry (IUPAC) is an international, non-governmental organization whose purpose is to address many global issues involving the chemical sciences. The primary goal of the IUPAC is fostering worldwide communications in the chemical sciences.
