7.0 HALOALKANES (ALKYL HALIDES) 1
a) Give the name of haloalkanes according to the IUPAC nomenclature. b) Give the structural formulae of haloalkanes. c) Classify haloalkanes into primary, secondary and tertiary haloalkanes. d) Describe haloalkanes as compounds that contain polar bond and the carbon bearing the halogen is susceptible to nucleophilic attack. Learning Outcomes 7.1 Introduction 2
INTRODUCTION Haloalkanes or alkyl halide ❖ organic compounds with halogen atom as the functional groups (F, Cl, Br or I) ❖ general formula : CnH2n+1X ❖ Haloalkanes are reactive because the carbon-halogen bond is polar. ❖ Carbon bearing the halogen is susceptible to nucleophilic attack. 3
