WebJan 23, 2024 · The factors that will determine whether a species wants to share its electrons or not include electronegativity, size, and resonance. As Electronegativity Increases, Basicity Decreases: In general, if we move from the left of the periodic table to the right of the periodic table as shown in the diagram below, electronegativity increases. WebDec 7, 2015 · Arrange the following ions in order of basicity: (1) C H X 3 C O O X − (acetate) (2) P h O X − (phenoxide) (3) H O O X − (hydroperoxide) (4) H O X − (hydroxide) The first thing I see is that all of them have the same donor atom, i.e. oxygen. In both C H X 3 C O O X − and P h O X −, the charge is stabilized by resonance. recipe for chocolate fudge with nutsWebOne obvious way to look at it is the length of the bond, a shorter bond length (measured nucleus to nucleus) indicates a stronger bond, indicative of a more basic anion. (F-) bond length will be much shorter than (I-) because it is smaller and will squeeze closer. I hope that helps ya.
