Alkyl, Allyl and Vinyl Halides Differences

Characteristic

Alkyl Halides

Allyl Halides

Vinyl Halides

Definition

Alkyl halides have a halogen atom bonded to a saturated carbon atom.

Allylic halides have a halogen atom bonded to a carbon atom adjacent to a double bond.

Vinylic halides have a halogen atom bonded to a carbon atom directly attached to a double bond.

Carbon Hybridization

Saturated carbon atoms (sp3 hybridization).

Carbon adjacent to double bond (sp3 hybridization).

Carbon directly attached to double bond (sp2 hybridization).

Stability

Generally less reactive than allylic and vinylic halides.

More reactive than alkyl halides due to allylic resonance stabilization.

More reactive than alkyl halides, but less reactive than allylic halides.

Resonance Stabilization

No resonance stabilization.

Resonance stabilization due to the delocalization of electrons into the adjacent double bond.

No resonance stabilization.

Reactivity in SN1/SN2 Reactions

Reactivity depends on the carbon skeleton and nature of the halogen.

Generally, more reactive in SN1 reactions due to resonance stabilization of the carbocation intermediate.

Reactivity falls between alkyl and allylic halides in SN1/SN2 reactions.

Examples

Methyl bromide (CH3Br), Ethyl chloride (C2H5Cl), etc.

Allyl bromide (CH2=CH-CH2Br), Allyl chloride (CH2=CH-CH2Cl), etc.

Vinyl bromide (CH2=CH-Br), Vinyl chloride (CH2=CH-Cl), etc.

Alkyl Halide

Alkyl Halides are compounds where a halogen (fluorine, chlorine, bromine, or iodine) is attached to a carbon chain. Another name of Alkyl Halide is Haloalkanes, Halogenoalkanes. They play essential roles in the pharmaceuticals, plastics, and agriculture industries, contributing to various applications like medicine synthesis, plastic production, and pesticide formulation.

In this article, we will learn about Alkyl Halides, the Classification of Alkyl Halides, Uses, and others in detail.

What Are Alkyl Halides?

Alkyl halides are a type of organic compound composed of carbon, hydrogen, and halogen atoms. they are a subset of a general class of hydrocarbons. They consist of alkyl groups, which are hydrocarbon chains, bonded to one or more halogen atoms (fluorine, chlorine, bromine, or iodine). The general structure of alkyl halides involves a carbon atom from the alkyl group directly linked to a halogen atom....

Nomenclature of Alkyl Halides

Name Order: When naming alkyl halides, the name is typically written in the order of the alkyl group followed by the halogen. Locating the Carbon Chain: Identify the longest continuous chain of carbon atoms in the molecule. This chain gives the base name, and the carbon atoms are numbered. Numbering: Assign a number to each carbon in the chain, starting from the end nearest to the halogen. The goal is to give the halogen the lowest possible number. Prefix for Halogen: Add the prefix “fluoro,” “chloro,” “bromo,” or “iodo” to indicate the type of halogen present. Alphabetical Order: If there are multiple halogen substituents, list them in alphabetical order, using their prefixes. Isomers: Consider different structural isomers and select the one with the lowest numbering for the halogen....

Prepration of Alkyl Halides

Alkyl halides, or halogenated hydrocarbons, can be synthesized through various methods. One common approach involves the reaction between hydrocarbons and halogenating agents. In this synthesis, a hydrocarbon, typically an alkane or alkene, reacts with a halogen, such as chlorine or bromine. The reaction leads to the substitution of hydrogen atoms with halogen atoms in the hydrocarbon molecule. For example, in the chlorination of methane, one hydrogen atom in methane is replaced by a chlorine atom, resulting in the formation of chloromethane:...
