In a broad sense, haloalkanes that contain no hydrogen are stable in the troposphere and decompose only in the stratosphere.
22.
Alkenes also react with halogens ( X 2 ) to form haloalkanes with two neighboring halogen atoms in a halogen addition reaction.
23.
When full, the canister is completely filled with liquid haloalkane, and thus the volume of gas in the inhaler is about zero.
24.
Several classes of widely used haloalkanes are classified in this way chlorofluorocarbons ( CFCs ), hydrochlorofluorocarbons ( HCFCs ) and hydrofluorocarbons ( HFCs ).
25.
Haloalkanes react with ionic nucleophiles ( e . g . cyanide, thiocyanate, azide ); the halogen is replaced by the respective group.
26.
The Tercel was carried over to 1994 with no major changes Haloalkane, a non-CFC refrigerant was used in the air conditioning system.
27.
They are favored mechanism for tertiary haloalkanes, due to the stabilization of the positive charge on the carbocation by three electron-donating alkyl groups.
28.
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.
29.
In "'Birch alkylation "'the anion formed in the Birch reduction is trapped by a suitable electrophile such as a haloalkane, for example:
30.
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.
