Is it 'Phenyl' or 'Phenol' that is used as a cleaning agent?
2016年11月25日 · It's definitely not phenyl in there. This isn't stable and would immediately react to something else. Phenyle seems to be a name for a certain disinfecting agent out of pine oil. It says "phenolic type" on the bottom, so my best guess, without seeing the actual ingredient list, is that it is a derivative of phenol. Derivative means that phenol ...
Phenyl or benzene when naming compounds - Chemistry Stack …
2015年4月14日 · 13. You are confused about several overlapping but mostly unrelated issues. First, you are right that "benzyl" is the CX7HX8−--- C X 7 H X 8 − - - - radical and that "phenyl" is the CX6HX5−--- C X 6 H X 5 − - - - radical. Second, although "phenol" and "phenyl" sound almost the same, you would probably do well to think of them as ...
Why Phenyl Carbocation is unstable? - Chemistry Stack Exchange
2016年12月28日 · Phenyl carbonation is said to be unstable because the + charge on it cannot be stabilized by Resonance or any other electronic effects, so my question is that if the resonance occurs in the direction shown in the below picture the + charge can be delocalized to some extent, so will it adapt that ? organic-chemistry. resonance.
Inductive effect of phenyl ring - Chemistry Stack Exchange
2015年10月26日 · When considering phenyl group for what it is, a ring of six $\mathrm{sp^2}$-hybridized carbons, it is easy to see why it shows a strong electron withdrawing effect, and a weak electron donating effect. The electronegativity of the carbons make benzene a nucleophilic structure that does not easily give up its electron cloud.
Why is the phenyl shift happening? - Chemistry Stack Exchange
2024年4月28日 · 1 Answer. Sorted by: The need for shift is the much greater stability of the back bond stabilized cation formed on phenyl shift. Also Phenyl's migratory aptitude is greater than methyl due to higher electron density, and when the carbocation is getting back bond stabilized, in these type of cases, the migratory aptitude is strictly followed.
organic chemistry - How is the numbering in phenylpropenes?
2016年11月2日 · Here, the propene part is the main chain. Double bond gets more priority than phenyl substituent, so numbering is started from that end. Phenyl group gets number 3. So the more correct name should be 3-phenyl-1-propene. However, writing 3-phenylpropene does not cause any ambiguity (as the numbering is started from the double bond end) edited.
organic chemistry - What is the priority of a phenyl group in a ...
2015年3月9日 · to be 1-phenylbut-4-ene Where is the priority here? No source I know of tells me of where the priority of the phenyl group lies. It is wrong. The book states it is 4-PhenylBut-1ene. What is the priority of the phenyl group?
Phenyl group in proton NMR - Chemistry Stack Exchange
The ppm-scale has been chosen to remove the differences between different proton’s signals (so 2ppm 2 p p m will always be 2ppm 2 p p m) and therefore the coupling splits will vary with the strength of the NMR magnet, which is why they aren’t given in ppm, but rather in Hz. If you have multiple protons of the same type, the coupling value ...
organic chemistry - Which is more stable? A phenyl carbanion or a ...
The lone pair would be more stable in an sp2 orbital rather than a p orbital. Hybridization is a way to answer the OP's question. The C-H bond in benzene is $\ce{sp^2}$ while the C-H bond in ethylene is $\ce{sp^{2.2}}$, consequently the phenyl carbanion is more stable. If this question is reopened I will write more. $\endgroup$ –
Why are vinylic and arylic carbocations highly unstable?
2014年5月7日 · I have checked the internet and read quite a few books, but I still am not able to understand why vinylic and arylic carbocations are highly unstable. What I found while surfing the internet is: For
