Overview

Haloalkanes and haloarenes are organic compounds in which one or more hydrogen atoms of hydrocarbons are replaced by halogen atoms (F, Cl, Br, I). These compounds are not found in nature and are synthesized in laboratories. They are widely used in industries and households as solvents, refrigerants,

Key Concepts

Haloalkanes are named by selecting

Haloalkanes are named by selecting the longest carbon chain containing the halogen and numbering it so that the halogen gets the lowest possible numbe

Haloalkanes can be prepared from alkanes

Haloalkanes can be prepared from alkanes via free radical halogenation (for Cl and Br), from alcohols using HX, PX₃, PX₅, or SOCl₂. Haloarenes are pre

Haloalkanes and haloarenes are polar but

Haloalkanes and haloarenes are polar but immiscible in water due to inability to form hydrogen bonds. They have higher boiling points than parent hydr

Haloalkanes are more reactive than haloarenes

Haloalkanes are more reactive than haloarenes in nucleophilic substitution because the C–X bond in haloarenes gains partial double bond character due

Important polyhalogen compounds include chloroform (CHCl₃)

Important polyhalogen compounds include chloroform (CHCl₃), iodoform (CHI₃), DDT, and BHC. Chloroform is stored in dark bottles to prevent oxidation t
