  1. IUPAC Nomenclatureof Alkyl Halides

  2. IUPAC Nomenclature There are several kinds of IUPAC nomenclature. The two that are most widely used are:functional class nomenclaturesubstitutive nomenclature Both types can be applied to alcohols andalkyl halides.

  3. CH3CH2CHCH2CH2CH3 H I Br Functional Class Nomenclature of Alkyl Halides Name the alkyl group and the halogen asseparate words (alkyl + halide) CH3F CH3CH2CH2CH2CH2Cl

  4. CH3CH2CHCH2CH2CH3 H I Br Functional Class Nomenclature of Alkyl Halides Name the alkyl group and the halogen asseparate words (alkyl + halide) CH3F CH3CH2CH2CH2CH2Cl Methyl fluoride Pentyl chloride 1-Ethylhexyl bromide Cyclohexyl iodide

  5. CH3CHCH2CH2CH3 Br CH3CH2CHCH2CH3 I Substitutive Nomenclature of Alkyl Halides Name as halo-substituted alkanes. Number the longest chain containing thehalogen in the direction that gives the lowestnumber to the substituted carbon. CH3CH2CH2CH2CH2F

  6. CH3CHCH2CH2CH3 Br CH3CH2CHCH2CH3 I Substitutive Nomenclature of Alkyl Halides Name as halo-substituted alkanes. Number the longest chain containing thehalogen in the direction that gives the lowestnumber to the substituted carbon. CH3CH2CH2CH2CH2F 1-Fluoropentane 2-Bromopentane 3-Iodopentane

  7. Cl CH3 CH3 Cl Substitutive Nomenclature of Alkyl Halides Halogen and alkyl groupsare of equal rank when it comes to numberingthe chain. Number the chain in thedirection that gives the lowest number to thegroup (halogen or alkyl)that appears first.

  8. Cl CH3 CH3 Cl Substitutive Nomenclature of Alkyl Halides 5-Chloro-2-methylheptane 2-Chloro-5-methylheptane

  9. Classification Alcohols and alkyl halides are classified asprimary secondary tertiaryaccording to their "degree of substitution." Degree of substitution is determined by countingthe number of carbon atoms directly attached tothe carbon that bears the halogen or hydroxyl group.
