Web27 mei 2024 · Why is the Acylium ion stable? The acylium ion is stabilized by the positive mesomeric effect of the lone pair of electrons on the oxygen atom onto the empty p-orbital of the C+. This helps achieve octet completion of the carbon atom, and thus imparts stability to the carbocation.
Web5 okt. 2024 · 2. when we talk about stability of halogen anions we say, I X − > B r X − > C l X − > F X −, and the reason is that "the negative charge (the electrons) have more space to move about in the larger halogen".

WebThe stability of a complex particle (ion or molecule) in solution is determined by the nature of the central atom and the ligands. The most important characteristics of the central atom, determining the stability of the complex compound, are the degree of oxidation (charge on the central ion in the case of ionic complexes), the dimensions, and the electronic structure.
