Interpretation Introduction

Interpretation:

Hydrocarbon core of the given compound has to be named.

Concept Introduction:

Bicyclic compounds: Compounds that contain two fused rings called bicyclic compounds.

Nomenclature of bicyclic compounds:

The organic compound naming is given by IUPAC (International Union for pure and applied chemistry). In the IUPAC names consist of certain rules for giving chemical names they are,

Identify and the parent: The term ‘Bicylo-’ is introduced in the name of the parent. Count the number of carbons excluding the bridge heads. In the compound below, each of the three paths has two carbons. These three numbers are ordered from largest to smallest, as [2.2.2] and placed in the middle of the parent

Identify and name substituents: If substituent is present, the parent must be numbered properly in order to assign the locants to the substituent. To number the parent, start at one of the bridgeheads and begin numbering along the longest path, then go to the second longest path, and finally go along the shortest path.

Arrange the substituents alphabetically.

In the complex substituent in compounds, the substituent name is assigned by a name each of them based on numbers going away from the parent.
