Overview

Haloalkanes and haloarenes are important halogen derivatives of hydrocarbons. Haloalkanes are the halogen derivatives of alkanes, while haloarenes are the halogen derivatives of aromatic hydrocarbons with the halogen directly attached to the aromatic ring. These compounds are widely used in organic

Key Concepts

Halogen derivatives of alkanes

Halogen derivatives of alkanes, alkenes, alkynes, and arenes are grouped into aliphatic halogen compounds and aromatic halogen compounds. Haloalkanes

Haloalkanes are monohalogen or polyhalogen derivatives

Haloalkanes are monohalogen or polyhalogen derivatives of alkanes with general formula C_nH_(2n+1)X. Monohaloalkanes are classified as primary, second

Monohalo compounds may contain C(sp3)

Monohalo compounds may contain C(sp3)-X, C(sp2)-X, or C(sp)-X bonds. Allylic and benzylic halides contain C(sp3)-X bonds, vinylic and aryl halides con

Haloalkanes can be prepared from alkanes

Haloalkanes can be prepared from alkanes by free-radical halogenation and from alkenes by addition of halogen acids. Chlorination of methane gives a m

During addition of HX to

During addition of HX to an unsymmetrical alkene, the negative part goes to the carbon with fewer hydrogens and hydrogen goes to the carbon with more
