Nomenclature of JEE (Main+Advance) Integrated Course Alkyl Halides
The nomenclature of alkyl halides follows the same principles as other organic compounds, with the addition of the halogen atom as a substituent on the alkyl chain. The IUPAC system is commonly used for naming alkyl halides, and the following rules are followed:
- Identify the parent chain: Identify the longest continuous chain of carbon atoms that contains the halogen atom. This chain forms the basis of the name.
- Number the carbon atoms: Number the carbon atoms in the parent chain, starting from the end nearest to the halogen atom. If there is a tie, start from the end nearest to the first branch point.
- Identify the halogen: The halogen is named as a substituent, using the prefix fluoro-, chloro-, bromo-, or iodo-, depending on the halogen atom.
- Assign a locant to the halogen: The locant (number) of the carbon atom to which the halogen is attached is placed before the prefix.
- Include the name of the alkyl group: If there are alkyl groups attached to the parent chain, they are named using the appropriate prefix (methyl-, ethyl-, propyl-, etc.) and their locants are placed before the parent chain name.
- Indicate the stereochemistry: If there are chiral carbon atoms in the molecule, the stereochemistry is indicated using the R/S system or the E/Z system.
Here are some examples of nomenclature for alkyl halides:
- 2-bromo-3-methylbutane (bromine attached to the second carbon atom, methyl group attached to the third carbon atom of a butane chain)
