An alkyl halide is a compound that contains a halogen atom (fluorine, chlorine, bromine, or iodine) bonded to a carbon atom within an alkyl group. Alkyl halides are often used as intermediates in organic synthesis reactions and have diverse applications in industries such as pharmaceuticals and agriculture.
You can start with 2- propanol, react it with sodium so that you get the alkoxide ion of the two reactant then follow it with an alkylhalide so that a nucleophilic substitution reaction can take place to form 2-methoxypropane. An alkylhalide to be used here be an alkyl of any of the halogen group or aklylsulfonate/aklylsulfate can be used also instead of alkylhalide
Alkylhalides can dissolve in organic solvents due to similar intermolecular forces at play. The polar nature of alkylhalides (due to the halogen) allows them to interact with the solvent molecules through dipole-dipole interactions or dispersion forces. This leads to a homogenous mixture of alkylhalide and organic solvent.
A reaction with alkyl halides in NaI with acetone is by the Sn2 mechanism. The rate for an Sn2 mechanism is directly proportional to the concentration of the nucleophile: rate = k[nucleophile][alkylhalide] If the iodine solution (the nucleophile) is half as concentrated, then the rate will also be halved. rate = k [nucleophile]/2 [alkyl halide]
