Question

How to convert alkene to alkyl halide?

Answer 1

Hint: An alkene is a hydrocarbon with a carbon–carbon double bond in chemistry. The term is often used interchangeably with olefin, which refers to any hydrocarbon with one or more double bonds. The IUPAC, on the other hand, advises that the term "alkene" be reserved for acyclic hydrocarbons with just one double bond.

Haloalkanes are a class of chemical compounds made up of alkanes that contain one or more halogens. While the distinction is not always made, they are a subset of the general class of halocarbons. Haloalkanes are commonly used in industry, and as a result, they go by a variety of chemical and trade names.
Alkyl halide is formed when alkene is treated with HX.
\[C{H_2} = C{H_2} + HX \to C{H_{3}} - C{H_2} - X\]
When X = Br we get,
\[C{H_2} = C{H_2} + HBr \to C{H_{3}} - C{H_2} - Br\]
Ethyl bromide is formed here
Haloalkanes are similar to parent alkanes in that they are colourless, odourless, and hydrophobic. Chloro-, bromo-, and iodoalkanes have higher melting and boiling points than comparable alkanes, which scale with atomic weight and number of halides. Because of the improved polarizability, the intermolecular forces have become stronger, shifting from London dispersion to dipole-dipole interaction. Tetrachloromethane ($CCl_4$) is a liquid, while tetraiodomethane ($CI_4$) is a solid.

Note:
At normal temperature and strain, the halogens are the only periodic table group that includes elements in three of the major states of matter. When halogens are bound to hydrogen, they all produce acids. The majority of halogens are made from rocks or salts. Chlorine, bromine, and iodine, the middle halogens, are often used as disinfectants. The most common form of flame retardant is organic bromides, whereas elemental halogens are hazardous and can be fatal.
