Iodine is a nonmetallic halogen element in Group 17 of periodic table; atomic number 53; atomic mass 126.9; melting point ca 114 C; boiling point ca 184 C; specific gravity 4.93 g/cm3; oxidation states: 7,5,1,-1; [Kr] 4d10 5s2 5p5. Iodine is a nearly black poisonous, corrosive solid at room temperature and readily sublimes to a deep violet vapour, the colour of which is responsible for its name from Greek. It is insoluble in water, soluble in common solvents. Iodine is required in small amounts in human body for the function of the thyroid gland. Iodine forms many important compounds of iodine such as iodine(V)oxide, potassium iodide, iodine trichloride and iodoform of an Iodine containing organic compound.

The related name, iodate indicates any salt of iodic acid containing the IO3- radical; KIO3 (potassium iodate) and NaIO3 (sodium iodate) are the most important salts. Whereas, iodide indicates any compound of iodine with a more electropositive element or group such as such as CH3CH2I or any binary compound of iodine which may contain the I- radical and which may be considered to be derived from hydriodic acid (HI); KI and NaI are examples.

Dietary iodine is reduced to iodide, absorbed in the intestines, and later taken up from the bloodstream by the thyroid gland for incorporation into thyroid hormones. Iodine is applied in the treatment of thyrotoxic crisis to produce a thyroid gland of firm texture suitable for operation, it avoids the increased vascularity and friability of the gland with increased risk of haemorrhage. Iodine has powerful bactericidal activity. It is used is used for disinfecting skin and for the treatment of minor wounds and abrasions. Iodine has been used in the purification of drinking water in case of amoebicidal and bactericidal emergencies. Iodine is used as a component in germicides and disinfectants with surfactants to carry iodine. Iodine is used in the treatment of herpes simplex, keratoscleritis and preventing the development of goitre.

Inorganic iodide compounds are soluble in water and hygroscopic except a few inorganic iodides such as copper iodide. Their refractive indexes and specific gravities are higher than the corresponding chlorine and bromine analogues. The important iodides commercially are potassium iodide (KI), sodium iodide (NaI), hydrogen iodide (HI), and polyiodides.

Potassium and sodium Iodide are used in photography and as analytical reagents. They are used in the measurement of the energy of gamma rays, by measuring the amplitude of pulses of light generated by electrons which are excited by the gamma rays. They are used as nutrition supplements to prevent goitre and other iodine deficiency in human body. They are used in organic synthesis as well. Potassium iodide has been used as a mucolytic agent. Potassium iodide is used as a heat stabilizer and a catalyst in synthetic fiber manufacturing.

Hydriodic acid is the aqueous pale yellow solution of  gas hydrogen iodide; the solution of 59% hydrogen iodide has constant-boiling. It is a strong acid and reducing agent used as raw materials for pharmaceuticals. analytical reagent as well as in organic synthesis and making iodine salts.

Inorganic iodate compounds, prepared generally by the oxidation of iodine with iodic acid or by electrolytic oxidation of iodide solutions, are stable oxidizers at room temperature though they lose oxygen at higher temperatures. Iodic acid (hydrogen iodate), a white crystalline powder, is a strong inorganic acid; highly corrosive oxidizing agent; decomposes at 110 C. It is used as a reducing agent in organic synthesis. Metallic iodates are explosive or flammable when contact with organic combustible materials. The important iodates commercially are potassium iodate and calcium iodate; white, odorless crystaline powder soluble in water, insoluble in alcohol. They are used as analytical reagents and in the manufacture of disinfectants, antiseptics, deodorants, medicines and other iodine compounds as well as oxidation of sulphur dyes. They are used in baking ingredient conditioner and as animal feed and food supplement for the treatment of their deficiency.

Organic iodines are very useful reagents as they have lower heat of formation than chlorine or bromine analogues. Aliphatic Iodides are used as alkylating agents in synthetic organic chemistry. Iodoform is a simple structural compound; greenish yellow hexagonal solid with a strong, penetrating odor; containing about 96 per cent of iodine; melting point 119 C; soluble in chloroform and ether and somewhat in alcohol and water: used as a topical anti-infective, applied to the skin. Iodoacetic acid is used in biochemical research; it alkylates free thiol groups but not disulfide bridges. methyl iodide, also called iodomethane, is a colorless liquid that turns brown on exposure to light; used in microscopy and in testing for pyridine. It is irritating to skin and mucous membranes and is a suspected carcinogen. Ethylene diamine dihydroiodide is used in animal feeds to prevent deficiency of iodine. Iodine organic compounds are useful in dye industry for the high bright colors as well as pharmaceutical industry. They are important for the production of X-ray contrast media and for the formulating antiseptics.

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.
