A subset of the general class of halocarbons, alkyl halide, is an organic molecule in which one or more halogen atoms are replaced for one or more hydrogen atoms.
Have you ever wondered what keeps your precious chocolate ice cream from turning into a chocolate shake? Obviously, the answer is a freezer, but what is the scientific way to answer it? Refrigerators in our kitchens use refrigerants such as chlorofluorocarbons (an alkyl halide), which helps freeze our ice creams.
However, the impacts of ozone-depleting substances (ODS) on the stratospheric ozone layer have been a source of worry. In the 1970s, various countries, notably the United States, banned the use of chlorofluorocarbons (CFCs) as aerosol sprays. These threatening yet useful gases here are an eminent example of what we are going to study in this article, the alkyl halides in organic chemistry.
An alkyl halide is an organic compound in which one or more hydrogen atoms in an alkane have been replaced by halogen atoms (fluorine, chlorine, bromine, or iodine)
In the above example, the letter R stands for alkyl group and the X for a halogen atom. We utilize the generalized formula R-X to describe an alkyl halide with 3 further categories on the basis of whether the halogen atom is bonded to a primary, secondary or tertiary carbon atom. (The primary carbon atom is the carbon which is attached to only one other carbon atom. Similarly for secondary and tertiary).
The question of how to name alkyl halides (also known as haloalkanes) can be answered in 2 ways: the common name and the IUPAC name. The simple steps to do so are listed below by taking CH3CH2CH2Br as an example:
Some of the examples of alkyl halides are listed below:
Note: Because there is just one carbon atom in the structure based on methane, there is no need to employ a number. The chloro is listed first alphabetically in the third example.
Alkyl halides are an integral part of organic chemistry and are widely used throughout, some of them being:
1. What is the general formula of Haloalkanes?
A: The compounds with the generic formula "RX," where R is an alkyl or a substituted alkyl group, and X is a halogen, are called haloalkanes or alkyl halides (F, Cl, Br, I).
2. What is the general formula of aryl halides?
A: Aryl halides have the generic formula ArX, where Ar is phenyl, branched phenyl, or aryl groups.
3. What is alkyl halide?
A: Alkyl halides, commonly known as haloalkanes or halogenoalkanes, are chemical compounds made up of one or more halogens.
4. What is alkyl halide and aryl halide?
A: Alkyl halides, commonly known as haloalkanes or halogenoalkanes, are chemical compounds made up of one or more halogens. Aryl halides are compounds with a halogen directly bonded to an aromatic ring carbon.
