Why are "vinylic" and "allylic" carbons named so?
Sep 24, 2023 · So, the carbons in vinyl group is "vinylic" carbon and the carbon in the extra methylene bridge is the "allylic" carbon. (Picture source) Regarding the origin of the word, the …
organic chemistry - GOC allylic,vinylic, benzylic positions ...
Carbo-cations may be stabilized by: (a) π-bonds only at allylic position (b) π-bonds only at vinylic position (c) π-bonds at allylic and benzylic position also (d) -I effect While the answer is …
Why are vinylic and arylic carbocations highly unstable?
Mar 13, 2018 · For a positive center to be attached to a more electronegative group is destabilizing. Hence the vinylic cation is less stable than a typical alkyl cation. Things are even …
organic chemistry - Why do vinylic carbocations have an empty …
Oct 31, 2023 · Clarification: If I wasn't completely clear, my main question is why vinylic carbocations have an empty sp2 orbital while tertiary carbocations have an empty p orbital. I …
organic chemistry - Why do vinylic carbocations generally not …
Apr 30, 2018 · This is why rearrangements in vinylic carbocations don't occur. (There is a Russian Chemical Reviews article that explains all this, but it's hard to get a copy of this, and their …
Why are the vinylic bonds in alkenes slightly polar?
May 11, 2013 · when searching in the internet about why are alkenes more polar than alkanes (but still they are non-polar), they are always saying that the double bond is more polarizable , …
Elimination from Vinylic Halides - Chemistry Stack Exchange
Oct 2, 2015 · On the other hand, the elimination reaction at a vinylic carbon is quite facile. Here as the base removes a proton we build up negative charge on an $\ce{sp^2}$ hybridized carbon. …
What is the difference between an Aryl Halide and a Vinyl Halide?
May 4, 2021 · No, aryl halides are not a type of vinyl halides. A compound is called an aryl halide when it contains a halogen group directly attached to an aromatic system.
Which is more stable? A phenyl carbanion or a disubstituted …
The lone pair on the benzene is in the plane of the ring and hence orthogonal to the conjugated $\pi$-system so that it cannot interact with it. It is $\ce{sp^2}$ hybridized just like the vinylic …
organic chemistry - Which is more stable — a carbanion on a …
The larger the electron affinity, the more tightly the electron was held. Stable carbanions hold their electron more tightly than less stable carbanions. The electron affinity of the allyl anion was …
