SeO 2 + 2NaOH → Na 2 SeO 3 + H 2 O [ Check the balance ] Selenium(IV) oxide react with sodium hydroxide to produce sodium selenite and water. Title: SeO2/H2O2/H2O-Dioxane: A New Catalytic System for Trans Dihydroxylation of Olefins VOLUME: 4 ISSUE: 4 Author(s): Pranjal Gogoi, Saikat Das Sharma and Dilip Konwar Affiliation:Organic Chemistry Division, Regional Research Laboratory, Jorhat–785006, Assam, India. Hence the reaction setup must be maintained under a fuming cupboard. Following rearrangement and loss of water, a second equivalent of water attacks the alpha position. The mechanism of oxidation of -CH 2 C(O)R group by SeO2 has been well investigated. Error: equation SeO2+KOH=K2SeO4+H2O is an impossible reaction Please correct your reaction or click on one of the suggestions below: SeO2 + KOH = H2O + K2SeO3 SeO2 + KOH = KO2 + SeOH SeO2 + KOH = H2 + K2SeO4 Instructions and examples below may help to solve this problem You can always ask for help in the forum * SeO 2 is an acidic oxide and dissolves in water to form selenous acid, H 2 SeO 3. Hey there partner, You get carbonated or fizzy water. In many cases a … (when the CO2 returns to a gas, it is endothermic…requires input heat). Mechanism. Add / Edited: 11.10.2014 / Evaluation of information: 5.0 out of 5 / number of votes: 1. The solubilities of the systems CeO2-SeO2-H2O and Ce2O3-SeO2-H2O were studied at 100 degreesC. Variety of solvents can be employed. Please register to post comments. The process requires that the cold/cool water be saturated with CO2. For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but PhC2H5 + O2 = PhOH + CO2 + H2O will; Compound states [like (s) (aq) or (g)] are not required. The oxidation of carbonyl alpha methylene positions begins with attack by the enol tautomer at the electrophilic selenium center. If you do not know what products are enter reagents only and click 'Balance'. SeO 2 in water: a mild and efficient promoter for deprotection of acetyl, methoxymethyl and tetrahydropyranyl ethers and sequel oxidation of methyl/methylene carbons of alpha carbonyl carbon. ... Сoding to search: SeO2 + 2 NaOH = Na2SeO3 + H2O.
