- In a broad sense, haloalkanes that contain no hydrogen are stable in the troposphere and decompose only in the stratosphere.
- Alkenes also react with halogens ( X 2 ) to form haloalkanes with two neighboring halogen atoms in a halogen addition reaction.
- When full, the canister is completely filled with liquid haloalkane, and thus the volume of gas in the inhaler is about zero.
- Several classes of widely used haloalkanes are classified in this way chlorofluorocarbons ( CFCs ), hydrochlorofluorocarbons ( HCFCs ) and hydrofluorocarbons ( HFCs ).
- Haloalkanes react with ionic nucleophiles ( e . g . cyanide, thiocyanate, azide ); the halogen is replaced by the respective group.
- The Tercel was carried over to 1994 with no major changes Haloalkane, a non-CFC refrigerant was used in the air conditioning system.
- They are favored mechanism for tertiary haloalkanes, due to the stabilization of the positive charge on the carbocation by three electron-donating alkyl groups.
- In general, the reaction of haloalkane with potassium hydroxide can compete with an S N 2 nucleophilic substitution reaction by OH " a strong, unhindered nucleophile.
- In "'Birch alkylation "'the anion formed in the Birch reduction is trapped by a suitable electrophile such as a haloalkane, for example:
- Only haloalkanes which contain chlorine, bromine, and iodine are a threat to the ozone layer, but fluorinated volatile haloalkanes in theory may have activity as greenhouse gases.
- Only haloalkanes which contain chlorine, bromine, and iodine are a threat to the ozone layer, but fluorinated volatile haloalkanes in theory may have activity as greenhouse gases.
- These methods are so reliable and so easily implemented that haloalkanes became cheaply available for use in industrial chemistry because the halide could be further replaced by other functional groups.
- In the presence of a base, haloalkanes alkylate alcohols, amines, and thiols to obtain ethers, " N "-substituted amines, and thioethers respectively.

- To compare, its structural isomer, 1-chloropropane, is instead an example of a primary ( 1?) haloalkane, as the chlorine-bound carbon atom has only one C-C bond.
- Haloalkane or alkyl halides are the compounds which have the general formula " RX " where R is an alkyl or substituted alkyl group and X is a halogen ( F, Cl, Br, I ).
- Some haloalkanes are still widely used for industrial cleaning, such as methylene chloride ( dichloromethane ), and as refrigerants, such as R-134a ( 1, 1, 1, 2-tetrafluoroethane ).
