The model of unsaturated α-lithio-ether CH 2 C(OH)Li has dual reactivity: structure 13 is the reaction intermediate when CH 2 C(OH)Li serves as an acyl anion equivalent; structure 10 is the real reaction structure for CH 2 C(OH)Li serving as a carbenoid, and the configuration of ...
The results of ion-beam studies, negative-ion photoelectron spectroscopy, and ion-molecule reaction data allow us to specify the hydride–water bond energy D0298(H--H2O)=14.4±1.0 kcal mol-1 (0.62±0.04 eV). The heat of formation of H3O-, -37.5±1.0 kcal mol-1, and the proton ...
sodium acetate is a basic salt; the acetate ion will deprotonate water, thereby increasing the ph of the solution. the basic salt are formed in the neutralization reaction between a strong base and a weak acid. q4 what are the advantages of acetate? this is among the most flexible ...

The reaction of equimolar amounts of UFand HO in hydrogen fluoride results in the partial dissolution of UF, yielding a blue-green solution from which the new salt oxonium hexafluorouranate(V)(HOUF) could be isolated as a green crystalline solid. Calorimetric measurements showed HOUFto decompose...
