Causes of Wavy Vision: Wavy vision is caused due to some underlying problem in the eye and the adjoining parts. Some similar problems are: Ocular Migraines: It is a condition which is caused due to some problem in the ophthalmic nerves coming from the brain.
Key Points. 1  Hydrogen halides are binary compounds of halogens with hydrogen. 2  Metal halides are compounds of halogens and metals. 3  Interhalogen compounds are formed when halogens react with each other.  Halogenated compounds, or organic halides, are organic compounds that contain halogen atoms. In the human body, some halogens perform multiple regulatory functions, while others are not essential. Organohalogens are synthesized through the nucleophilic abstraction reaction.
(Redirected from Free radical halogenation). In organic chemistry, free-radical halogenation is a type of halogenation. This chemical reaction is typical of alkanes and alkyl-substituted aromatics under application of UV light.The reaction is used for the industrial synthesis of chloroform (CHCl 3), dichloromethane (CH 2 Cl 2), and hexachlorobutadiene.It proceeds by a free-radical chain mechanism. This is because less energy is required to form the H-Br and tertiary radical (380 â 366 kJ/mol = +14 kJ/mol). 2  This value is 17 kJ/mol less than the secondary radical formation. 3  Iodine does not even participate in free-radical halogenation because the entire reaction is endothermic.
