Ethyl iodide (also iodoethane) is a colorless flammable chemical compound. It has the chemical formula C 2 H 5 I and is prepared by heating ethanol with iodine and phosphorus . [ 2 ] On contact with air, especially on the effect of light, it decomposes and turns yellow or reddish from dissolved iodine.
Ether synthesis by reaction of salicylaldehyde with chloroacetic acid and sodium hydroxide [1] The Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol . This reaction was developed by Alexander Williamson in 1850. [2]
Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a white, water-soluble solid comprising a 1:1 mix of sodium cations (Na +) and iodide anions (I −) in a crystal lattice. It is used mainly as a nutritional supplement and in organic chemistry.
1,2-Diiodoethane can be prepared by the reaction of ethylene with iodine (I 2): [2] C 2 H 4 + I 2 ⇌ C 2 H 4 I 2. 1,2-Diiodoethane is most commonly used in organic synthesis in the preparation of samarium(II) iodide or ytterbium(II) iodide in an inert solvent such as THF. [3] Sm + ICH 2 CH 2 I → SmI 2 + H 2 C=CH 2
MeI can also be used to prepare dimethylmercury, by reacting 2 moles of MeI with a 2/1-molar sodium amalgam (2 moles of sodium, 1 mol of mercury). Iodomethane and other organic iodine compounds do form under the conditions of a serious nuclear accident, [ 11 ] after both Chernobyl and Fukushima , Iodine-131 was detected in organic iodine ...
For example, sodium acetate dissociates in water into sodium and acetate ions. Sodium ions react very little with the hydroxide ions whereas the acetate ions combine with hydronium ions to produce acetic acid. In this case the net result is a relative excess of hydroxide ions, yielding a basic solution. Strong acids also undergo hydrolysis.
