Haloalkanes and HaloarHaloarenesenesenesenesenes

• name haloalkanes and haloarenes according to the IUPAC system of nomenclature from their given structures; • describe the reactions involved in the preparation of haloalkanes and haloarenes and understand various reactions that they undergo; •correlate the structures of haloalkanes and haloarenes with various types of reactions;

What is the rule for naming haloalkanes?
Their names are derived by prefixing the words fluoro, chloro, bromo or iodo (according to the halogen atom present) to the name of the longest straight chain present in the compound.
In naming haloalkanes, the numbering of carbon atoms in the longest chain is done from the end from which the halogen atom is nearer.

Nomenclature of Haloarenes Aryl halides are named by prefixing “halo” to the name of the parent aromatic hydrocarbon. If there is more than one substituent on the ring then the relative positions of the substituents are indicated by mathematical numerals.

Nomenclature of Haloalkanes

Initially, there was no proper system for the naming of compounds. Mostly there were trivial names that were used depending upon the country and region. These trivial names were based on the discoverer or the nature of the compound or its place of discovery. The system of trivial names was not standard and led to much confusion, thus raising the ne

Rules of Nomenclature

Find the longest carbon chain.Number the longest carbon chain such that the carbon atom(s) to which the halogen(s) is/are attached get the lowest number(s).Multiple halogen atoms are labelled with the Greek numerical prefixes such as di(for two halogen atoms), tri(for three halogen atoms), and tetra(for four halogen atoms) to denote the number of iden

The Methodology of Writing Name

First, write the root word for the parent hydrocarbon (depending upon the no. of carbon atoms in the longest carbon chain).Secondly, calculate the number of halogen atoms present. If there are multiple halogen atoms present, then arrange the halogens alphabetically in the prefix, labelling them with their respective po

Nomenclature of Haloarenes

Aryl halides are named by prefixing “halo” to the name of the parent aromatic hydrocarbon.If there is more than one substituent on the ring then the relative positions of the substituents are indicated by mathematical numerals.In the common system, the relative position of two groups is shown by prefixes ortho, meta or para. byjus.com
