Question

what are alkyl halides. explain

Answer 1

Alkyl halides (also known as haloalkanes) are compounds in which one or more hydrogen atoms in an alkane have been replaced by halogen atoms (fluorine, chlorine, bromine or iodine). Alkyl halides fall into different classes depending on how the halogen atom is positioned on the chain of carbon atoms; there are some chemical differences between the various types.

Answer 2

Alkyl halides are formed by addition of halogens to the chained carbon atoms forming hydrocarbons...
To form Alkyl Halide one Hydrogen gets detached from parent chain and one halogen gets added...

There are many methods to form an alkyl Halide..
Halogens like Chlorine, Bromine, Iodine gets attachment to the parent chain..

Fluorine is very much reactive, so compounds of fluorine are not so stable...

There are some catalysts and agents used to add halogens to Alkanes, Alkenes or alkynes...
