Dodecylbenzene (C12H25C6H5) with sodium hydroxide (NaOH)= no reaction? Fatty alcohol (C12-16) with sodium hydroxide = Fatty alcohol salt? Monoétanolamine (C2H7NO) with sodium hydroxide = reaction? Ammonia solution with sodium hydoxide = NH3 (gas) with water?
Also I'm a little confused about how to right a Sn1 and Sn2 reaction. Could someone please offer help in that as well. Thank You first of all, you can't say in the absence of a catalyst like sulfuric acid because your butyl alcohol is in sulfuric acid second, what do you think ar...
The reaction between an acid and an alcohol in the presence of concentrated sulfuric acid to produce ester and water, in essence, is the reaction of carboxyl groups with hydroxyl groups to produce ester groups and water. Such as: Hydrolysis reaction. The substitution of -OH or -H in water ...
Transform name: In this case the transform corresponds with the Wittig reaction. Rating: An evaluation of the transform on chemical grounds. The rating should consider factors such as yield, cost, selectivity, reliablitiy, etc., but currently the rating function is very crude. Simplification: A...
