For example, the chlorofluorocarbons have been shown to lead to ozone depletion. Methyl bromide is a controversial fumigant. Only haloalkanes that contain chlorine, bromine, and iodine are a threat to the ozone layer , but fluorinated volatile haloalkanes in theory may have activity as greenhouse gases .
A hydrohalogenation reaction is the electrophilic addition of hydrogen halides like hydrogen chloride or hydrogen bromide to alkenes to yield the corresponding haloalkanes. [1] [2] [3]
The conversion of ethanol to ethylene is a fundamental example: [3] [4] CH 3 CH 2 OH → H 2 C=CH 2 + H 2 O. The reaction is accelerated by acid catalysts such as sulfuric acid and certain zeolites. These reactions often proceed via carbocation intermediates as shown for the dehydration of cyclohexanol. [5] Some alcohols are prone to dehydration.

For example, consider radical bromination of toluene: [5] bromination of toluene with hydrobromic acid and hydrogen peroxide in water. This reaction takes place on water instead of an organic solvent and the bromine is obtained from oxidation of hydrobromic acid with hydrogen peroxide. An incandescent light bulb suffices to radicalize.
Texas’ largest outbreak of measles in 30 years has reached 90 cases, the Texas Department of State Health Services said Friday. Thirty-two cases have been added since the department’s update ...
Chia seeds, greens, beans, berries, bananas and pears are prime examples of foods packed with gut-healthy fuel. But travel may be a time where supplements may be a fit, and Bulsiewicz explains ...
