Is benzofuran aromatic one?
Benzofurans are only weakly aromatic in nature and they are cleaved by many oxidative and reductive conditions. They are also prone to polymerisation in the presence of concentrated mineral acids and Lewis acids.
Which one is the example of benzofuran derivative?
This colourless liquid is a component of coal tar. Benzofuran is the “parent” of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants….Benzofuran.

What is the use of benzofuran?
Benzofurans are a type of psychoactive drug that are part of the amphetamine and phenylethylamine classes. They are known to produce feelings of euphoria and to stimulate the sympathetic nervous system, or the body’s system that is responsible for the instincts of flight or fight.
Why benzofuran is more stable than furan towards acid?
Why benzofuran is more stable than furan towards acid? Solution. But benzofuran is more resistant to acid than furan, since there is an additional benzene ring in the benzofuran, the presence of which leads to stabilization of the resonant structure, due to the redistribution of the electron density in the benzofuran.
What is the use of quinoline?
Quinoline is used principally for the manufacture of nicotinic acid, which prevents pellagra in humans, and other chemicals. Several methods are known for its preparation, and production of synthetic quinoline exceeds that from coal tar.
Is benzofuran planar?
Benzofurans are compounds with a planar structure having 10 pi electrons that include the lone pair on oxygen atom, which makes it more susceptible to electrophilic attack. Benzofurans have also made significant and distinctive contributions to biology.
What happens when thiophene undergoes Sulphonation?
Thiophenes undergo hydrogenolysis to form hydrocarbons and hydrogen sulfide. Thus, thiophene itself is converted to butane and H2S.
Is quinoline the same as quinine?
is that quinoline is (organic compound) any of a class of aromatic heterocyclic compounds containing a benzene ring fused with a pyridine ring; especially the simplest such compound, c9h7n while quinine is (pharmaceutical drug) a bitter colourless powder, an alkaloid derived from cinchona bark, used to treat malaria …
How many oxygen atoms are there in quinine?
two oxygen atoms
In the case of quiNINE chemical formula C 20 H. 24 N 202 See stamps for carbon. So we have 20 carbon atoms. We have 24 hydrogen atoms, two nitrogen atoms and two oxygen atoms.
Why is imidazole aromatic?
Imidazole – aromatic or not? Lastly, imidazole has 6 π – electrons (4 π- electrons from 2 π bonds and 2 π – electrons from the lone pair of electrons of -NH nitrogen atom), i.e., 4n+2 π – electrons where n = 1. Thus, imidazole is an aromatic molecule since it fulfills all of the criteria required to be one.
