WebMar 25, 2015 · Hyperconjugation does play a role in your example. Acetic acid ( p K a = 4.75) is a weaker acid than formic acid ( p K a = 3.75 ). To understand this we must consider the relative stabilities of both the ionized and unionized acids. In acetic acid there is a partial positive charge on the carbonyl carbon. Both the inductive effect and resonance ... WebAug 21, 2024 · Hyperconjugation from C-C to carbocation. Following the "rule" stated before, the stabilization of a carbocation will be best with an adjacent C-C bond. And this is in accordence with what we learn in school since the more alkyl groups nearby, the more stable is the carbacation.
IUPAC - hyperconjugation (H02924)
WebFeb 28, 2024 · Due to hyperconjugation, in the isopropyl carbocation, the net charge of +1 is shared by a total of seven atoms, one carbon atom and six hydrogen atoms. Thus, the net charge of +1 is delocalized over a greater number of atoms in the isopropyl carbocation than in the ethyl carbocation. The isopropyl carbocation should, therefore, be more stable ... WebAug 10, 2024 · The negative hyperconjugation is a type of resonance effect where there is a donation of electron density from a filled π- or p-orbital to a neighboring σ*-orbital.
