#NOMENCLATURE OF ORGANIC COMPOUNDS PPT FULL#
The full name for the alkane will include the names of any branches. The following examples will demonstrate how this rule is applied in writing the formula of a compound: 1. Atoms in molecules don’t the number of each atom: mono 1 di 2 tri 3 tetra 4 penta 5 Naming Molecular Compounds Prefix for first element in compound.
#NOMENCLATURE OF ORGANIC COMPOUNDS PPT PDF#
Organic compounds have their own special naming system. PDF organic chemistry - Alagappa University classification and nomenclature of organic compounds pdf classification of organic compounds ppt classification. This can be paraphrased as: The algebraic sum of the oxidation numbers of the elements and polyatomic ions in a chemical compound is zero. Molecular compounds w/ more than 2 elements are usually organic. The base name corresponds to the number of carbon atoms in the longest chain. in charge to the total oxidation number of the second, or negative, part of the compound. These are called secondary prefixes and are added immediately before the word roots in alphabetical order to denote the side chain or substituent groups. Longest chain rule 1)Determine the longest continuous (not necessarily straight) chain of carbon atoms. Nomenclature The name of every organic molecule has 3 parts: The parent name indicates the number of carbons in the longest continuous chain The suffix indicates what functional group is present The prefix tells us the identity, location, and number of substituents attached to the carbon chain Carbon substituents bonded to a long carbon chain. While adding the secondary suffix to primary suffix ,the terminal e of the primary suffix is dropped if the secondary suffix begins with a vowel but is retained if the secondary suffix begins with a consonant.ġ) Locants are placed immediately before the part of the name to which they relate.Ģ) The locant 1 is often omitted when there is no ambiguity.ĬH 3CH 2CH 2NH 2 Propane-1-amine is often named as Propamine.ĬlCH 2CH 2OH 2-Chloroethan-1-ol is often named as 2-ChloroethanolĬH 3CH 2CH 2CHO Butan-1-al is often named as 2-Chloroethanol.ġ) Primary prefix : A primary prefix is used simply to distinguish cyclic from acyclic compounds.įor ex: In case of carbocyclic compounds, a primary prefix ,cyclo is used immediately before the word root.Ĭyclo(Primary prefix) + Pent (word root) + ane( Primary suffix)Ģ) secondary prefix : Certain groups are not considered as functional groups but instead are treated as substituents. For each approved PPT you will get 25 Credit. Type Of carbon chainĢ) Secondary suffix : A secondary suffix is then added to the primary suffix to indicate the nature of the functional group present in the organic compound.

If the parent chain contains two, three, four or more double or triple bonds ,numerical prefixes such as di, tri ,tetra are added to the prefect primary.
