In primary (1°) haloalkanes, the carbon that carries the halogen atom is only attached to one other alkyl group. An example is chloroethane (CH 3 CH 2 Cl). In secondary (2°) haloalkanes, the carbon that carries the halogen atom has two C–C bonds. In tertiary (3°) haloalkanes, the carbon that carries the halogen atom has three C–C bonds.
A secondary deuterium isotope effect of slightly larger than 1 (commonly 1 - 1.5) is observed. There is no antiperiplanar requirement. An example is the pyrolysis of a certain sulfonate ester of menthol: E1 elimination Nash 2008, antiperiplanar relationship in blue Only reaction product A results from antiperiplanar elimination.
In a monohaloacetic acid, a single halogen replaces a hydrogen atom: for example, in bromoacetic acid. Further substitution of hydrogen atoms with halogens can occur, as in dichloroacetic acid and trichloroacetic acid. Haloacetic acids are a common contaminant in treated drinking water, particularly water subjected to chlorination.
The leaving site must be a primary carbon, because secondary and tertiary leaving sites generally prefer to proceed as an elimination reaction. Also, this reaction does not favor the formation of bulky ethers like di-tertbutyl ether, due to steric hindrance and predominant formation of alkenes instead.
Examples of organohalogens-chlorides. Halocarbons are typically classified in the same ways as the similarly structured organic compounds that have hydrogen atoms occupying the molecular sites of the halogen atoms in halocarbons. Among the chemical families are: [2] haloalkanes—compounds with carbon atoms linked by single bonds

Bromoethane, also known as ethyl bromide, is a chemical compound of the haloalkanes group. It is abbreviated by chemists as EtBr (which is also used as an abbreviation for ethidium bromide ). This volatile compound has an ether-like odor.
They belong to the haloalkanes, specifically the subgroup of halomethanes, and contains ten members. There are four members with only one kind of halogen atom: difluoromethane, dichloromethane, dibromomethane and diiodomethane.
