nomenclature of bicyclic compounds

Count the number of carbons to the left, and to the right, and above your bridgehead carbons.

The bicyclo compounds contain two fused rings with two connecting common carbon atoms known as bridge head carbons. IUPAC nomenclature of Fused bicyclic compounds .

Cycloalkanes only contain carbon-hydrogen bonds and carbon-carbon single bonds. Count the total number of carbons across the entire molecule. These numbers are a, b, and c in your IUPAC name, listed from highest to lowest. These compounds are known as cycloalkanes. Bicyclic Alkanes.

Cycloalkanes have one or more rings of carbon atoms. 1. 17.1 Nomenclature of Benzenes; 17.2a Criteria for Aromatic Compounds; 17.2b Aromatic vs Nonaromatic vs Antiaromatic; 17.3 The Effects of Aromaticity on SN1 Reactions and Acidity Basicity; 17.4 Aromaticity and Molecular Orbital Theory This is the parent name (eg. ten carbons in the system would be decane) IUPAC names for bicylic alkanes have the format bicyclo[a.b.c]parent name. To name bicyclic alkanes, you follow these three steps: Count the total number of carbons in the entire molecule. This tells you the alkane parent name that goes at the end. The carbon chain or covalent bond connecting these bridge heads is considered as a bridge. Fused ring systems that share more than two atoms are called bicyclic molecules. Many organic compounds found in nature contain rings of carbon atoms. The simplest examples of this class consist of a single, un-substituted carbon ring, and these form a homologous series similar to the unbranched … 2. Bridged Bicyclic Nomenclature (Three Rings) The bridgehead atom (one of the circled ones) must always be in the “1” position The name is formatted as bicyclo[ ringsize1.ringsize2.ringsize3 ]alkane
