14.2 Electrophilic Additions to Conjugated Dienes: Allylic
Electrophilic addition of HCl to a conjugated diene involves the formation of allylic carbocation intermediate. Thus, the first step is to protonate the two ends of the diene and draw the …
When the carbons of a conjugate diene all lie in the same plane, the π-molecular orbitals overlap. There are three conformations of butadiene. The (lower case) s prefix designates a …

2023年12月5日 · Another kind of resonance happens when a carbocation is next to a double bond, making it an allylic carbocation. Though not as strong as the first type, the more you …
Carbocation: Definition, Resonance, and Stability - Chemistry …
Allylic – If a carbon-carbon double bond is next to the positively-charged carbon, it is termed allylic carbocation—for example, CH 2 =CH-CH 2 +. Vinylic – If a carbon-carbon double bond is …
14.2: Resonance and Allylic Carbocations - Chemistry LibreTexts
Allylic carbocations are a common conjugated system. The positive charge of a carbocation is contained in a P orbital of a sp2 hybrizied carbon. This allows for overlap with double bonds. …
We use the same terminology to describe the conjugated carbocation (allylic carbocation) and the conjugated radical (allylic radical). We will look at the allylic carbocation first. It is particularly …
