Water reaction with halogens

Sodium azide is a toxic as well as an explosive substance (Patnaik, P. 1999. A Comprehensive Guide to the Hazardous Properties of Chemical Substances, 2nd e(j New York John Wdey Sons). Although inert to shock, violent decomposition can occur when heated at 275°C. Contact of solid or solution with lead and copper must be avoided. Reactions with halogens, carbon disulfide, or chromyl chloride can be explosive. Dissolution in water produces toxic vapors of hydrazoic acid. The salt is an acute poison causing headache, hypotension, hypothermia, and convulsion. 

Reactions with halogens are slow at room temperature but progress rapidly above 200°C forming ytterbium trihalides. All the trihalides namely, the YbCls, YbBrs, and Ybis with the exception of trifluoride, YbFs, are hygroscopic and soluble in water.

Alkanes are rather inert chemically. Aside from burning in air or oxygen to produce carbon dioxide and water (or carbon monoxide and water), the most characteristic reaction they undergo is reaction with halogen molecules, initiated with light. For example.

Ignites spontaneously in air ignites in CO2 ethereal solution also ignites spontaneously in air reacts explosively with water reactions with lower alcohols, halogenated hydrocarbons, ammonia, and oxidizing substances expected to be violent to explosive Ignites in air (slow oxidation) forms peroxide which explodes on friction (Davies 1961) reacts violently with water... 

Diethylberyllium ignites spontaneously in air, producing dense white fumes of beryllium oxide. Ether solution of this compound is also highly flammable, igniting spontaneously in air. It reacts explosively with water. Reactions with lower alcohols, halogens, halogenated hydrocarbons, ammonia, and oxidizers may proceed to explosive violence. 

When carbon forms four covalent bonds with halogen atoms the second quantum level on the carbon is completely filled with electrons. Most of the reactions of the Group IV tetrahalides require initial donation by a Lewis base (p. 91) (e.g. water, ammonia) which attaches initially to the tetrahalide by donation of its electron pair. Hence, although the calculated free energy of a reaction may indicate that the reaction is energetically favourable, the reaction may still not proceed. Thus we find that the tetrahalides of carbon... 

Reaction with Organic Compounds. Aluminum is not attacked by saturated or unsaturated, aUphatic or aromatic hydrocarbons. Halogenated derivatives of hydrocarbons do not generally react with aluminum except in the presence of water, which leads to the forma tion of halogen acids. The chemical stabiUty of aluminum in the presence of alcohols is very good and stabiUty is excellent in the presence of aldehydes, ketones, and quinones. 

Codeposition of silver vapor with perfluoroalkyl iodides at -196 °C provides an alternative route to nonsolvated primary perfluoroalkylsilvers [272] Phosphine complexes of trifluaromethylsilver are formed from the reaction of trimethyl-phosphme, silver acetate, and bis(trifluoromethyl)cadmium glyme [755] The per-fluoroalkylsilver compounds react with halogens [270], carbon dioxide [274], allyl halides [270, 274], mineral acids and water [275], and nitrosyl chloride [276] to give the expected products Oxidation with dioxygen gives ketones [270] or acyl halides [270] Sulfur reacts via insertion of sulfur into the carbon-silver bond [270] (equation 188)... 

It should be emphasized that the reactivity of IF3 is mild only in comparison with the other halogen fluorides (p. 830). Reaction with water is extremely vigorous but the iodine is not reduced and oxygen is not evolved ...
