IUPAC rules used for naming of Alkyl halides

• Select longest carbon chain, it is the parent chain;
• Longest chain must contain double or triple bond, if present;
• Number the alkyl or halo substituent carbon i.e. it should possess lowest number in the parent chain;
• Assign a number to each substituent;
• Write the name of substituent’s in alphabetical order while naming

Nomenclature of alkyl halides

(a) The name of the compound is 1-Iodobutane.
