Explain the term - Nomenclature'. State its need with reference to organic compounds. State the basic rules of Nomenclature by the trivial system - with suitable examples. Explain the longest chain rule and the smallest number for functional groups rule of Nomenclature by the IUPAC system-with suitable examples.

The correct decreasing order of priority for the functional groups of organic compounds in the IUPAC system of nomenclature is

The correct decreasing order of priority for the functional groups of organic compounds in the IUPAC system of nomenclature is

The correct decreasing order of priority for the functional groups of organic compounds in the IUPAC system of nomenclature is

Citing a few suitable examples write an explanatory note on the specific enzymes having trivial names under IUB system of enzyme nomenclature.

Names of organic compounds are under the latest guide line of IUPAC IUPAC means international union of pure and applied chemistry. The main rules are longest chain rule, lowest number rule etc. We have to include the rules for naming the substituetns, multiple bonds and even functional groups.

Write the IUPAC name of the following compound

The IUPAC name of [Co(H_2NCH_2CH_2NH_2)_2 (NO_2)NO_5 is bis(enthane-1,2-diamine) dinitrito-N-cobalt(III) nitrate.It follows the following rules that. (a)Cation is named first followed by anion. (b) Ligands are named in an alphabetical order before the name of the central atom/ion. ( c)Name of anionic ligands end in "o" (ex.chlorido) those of neutral (and if cation) ligands are the same except aqua for H_2O , ammine for NH_3 etc. (d)Prefixes mono,di,tri,etc.are used to indicate the number of individual ligand.When the name of the ligands include a numerical prefix, then terms bis, tris, tetrakis are used. (e)Oxidation state of the metal is indicated by Roman numeral in parenthesis. (f) For cationic and neutral complexes, the metal is named same as the element and for anionic complex, the name of metal ends with suffix-ate.For some metals, the Latin names are used in the complex anions , e.g., ferrate for Fe, argentate for silver etc. The correct IUPAC name of the coordination compound [Pt(NH_3)_2Cl(NH_2CH_3)] is :
