Alkyl Halide Reactivity Home Chemistry

Alkyl Halide Reactions. The functional group of alkyl halides is a carbon-halogen bond, the common halogens being fluorine, chlorine, bromine and iodine. With the exception of iodine, these halogens have electronegativities significantly greater than carbon. Consequently, this functional group is polarized so that the carbon is electrophilic

The Chemistry of Alkyl Halides Purdue University

Alkyl halides with three -substituents (C) are virtually unreactive in S N2 reactions. Secondary alkyl halides with no b- substituents (B) react more slowly than primary alkyl halides with two b- substituents (E), and the latter react more slowly than unbranched primary alkyl halides (D). Methyl halides (A) react most rapidly. 9.39 (b) (d) 9.40 (a)

7.1 Alkyl Halides Structure and Physical Properties

Alkyl halide classification is determined by the bonding pattern of the carbon atom bonded to the halogen as shown in the diagram below. Primary alkyl halides. In a primary (1°) haloalkane, the carbon bonded to the halogen atom is only attached to one other alkyl group. Some examples of primary alkyl halides include thecompounds below.

Add 2 mL of saturated aqueous sodium bicarbonate solution, a little at a time, while stirring. Cap the vial and shake it vigorously for 1 minute, venting frequently to relieve any pressure that is produced. Allow the layers to separate and then carefully transfer the lower alkyl halide layer to a dry 3-mL conical vial using adry Pasteur pipet.

A SN1 Reaction: Synthesis of tert-Butyl Chloride

This lab experiment proposes the synthesis of an alkyl halide by reacting the corresponding alcohol with a hydrogen halide in an easy and inexpensive SN1 reaction. 1,2 tert-Butanol reacts readily with HCl and forms the corresponding tert-butyl chloride at room temperature. SN1 mechanisms are unimolecular because its slow step is unimolecular.
