Haloalkanes and Haloarenes
13 lessons107 min7 simulations10 practice questions
Haloalkanes and haloarenes are hydrocarbons with one or more hydrogens replaced by halogen, on an sp³ or an sp² carbon. The chapter classifies and names them, relates the polar C–X bond to their physical and chemical behaviour, and builds the SN1 and SN2 mechanisms with their stereochemistry, before elimination, organometallics, haloarene reactions and the uses and hazards of polyhalogen compounds.
