APPLICATIONS

Halogenoalkanes, also known as haloalkanes or alkyl halides, are organic compounds in which one or more hydrogen atoms in an alkane have been replaced by halogen atoms, fluorine, chlorine, bromine or iodine. In carbon-halogen bond, halogens have significantly greater electronegativities than carbon except iodine. In result, this functional group is polarized so that the carbon is electrophilic and the halogen is nucleophilic. Halogenoalkanes are can be classified depending on the halogen atom position on the chain of carbon atoms. The carbon which is attached with the halogen atom is linked up with only one other alkyl group in primary halogenoalkanes, whereas directly linked up with two and three other alkyl groups in secondary halogenoalkanes and tertiary halogenoalkanes respectively. In some case, primary halogenoalkanes are counted even though there are no alkyl groups attached to the carbon with the halogen on it. Three characteristics provide important influences on the chemical behavior of halogenoalkanes, these are electronegativity, covalent bond strength and the relative stability of the corresponding halide anions.  Fluoroalkanes have the strongest of the carbon-halogen covalent bonds so that they are unreactive. This is stronger single bond than a carbon-carbon bond. The carbon-chlorine covalent bond is slightly weaker than a carbon-carbon bond, and the bonds to the other halogens are weaker. The stability may be estimated from the relative acidities of the H-X acids. All the hydrohalic acids are very strong, but with small differences in the direction HCl < HBr < HI, with the exception of HF. Halogenoarenes, also called haloarene, or aryl Halide, are  an organic compound in which one or more hydrogen atoms in an aromatic ring have been replaced by halogen atoms. The Haloarenes exhibit many differences compare to haloalkanes in the method of preparation and their chemical and phisical properties. Haloalkanes are used in as refrigerants, solvents, blowing agents, aerosol propellants, fire extinguishing media , and in semiconductor device fabrication. One of big consumption of halogenoalkanes (properly speaking, halogenoalkenes) is as a raw material to prepare plastics such as PVC [poly(chloroethene)] from chloroethene and PTFE [poly(tetrafluoroethene)] from tetrafluoroethene. Halogenoalkanes and halogenoarenes react with lots of compounds resulting in a wide range of different target substances. They are useful intermediates in making other organic compounds.

1-Bromopropane, also known as n-propyl bromide is a primary alkyl halide, with the formula CH3CH2CH2Br . 2-Bromopropane has bromine atom at the second position, also called isopropyl bromide. The formula is CH3CHBrCH3. They are bromine atom position isomers. They are colorless liquid, insoluble in water, but soluble in ethanol and ether. They are used as alkylating agents to introduce the alkyl groups to form carbon-carbon bonds in organic synthesis. They are also used as  intermediate to form alkylated amines and alkylated metallic compounds. The end products include pharmaceuticals, insecticides, quaternary ammonium compounds, flavours and fragrances. They are also used as solvent for industrial cleaning (degreasing, metal processing and finishing, electronics, aerospace and aviation), aerosols, textiles, adhesives , inks and coatings.
