Why furan do not show nucleophilic subtitution reaction?
Furan does not typically undergo nucleophilic substitution reactions because of its aromatic nature, which offers stability due to delocalization of the pi electrons in the ring. This makes furan less reactive towards nucleophilic attack compared to non-aromatic compounds.
Why pyrole is more basic then furan?
Pyrrol has a lone pair of electrons on the nitrogen atom, which is more available for donation compared to the lone pair on oxygen in furan. This makes pyrrole more basic than furan.
Why furan is more reactive than pyrrole and thiophene?
Furan is more reactive than Pyrrole because it is less stable as it contains an extra lone pair than that of pyrrole, which is available for attack of an acid, results in the destabilization of the ring.
What is the basicity of furan?
Furan is a heterocyclic compound that contains one oxygen atom in its five-membered ring structure. It can act as a Lewis base and can donate a lone pair of electrons, making it a weak base. Therefore, furan is considered to be a weakly basic compound.
What is another name for pentose pathway?
pentose phosphate pathway (also called phosphogluconate pathway, or hexose monophosphate shunt [HMP shunt])
Why Furan turns brown on exposure to air?
Furan is prone to oxidation reactions in the presence of air. This oxidation process causes the molecular structure of furan to change, leading to the formation of brown-colored compounds as byproducts. This is why furan turns brown when exposed to air.
Why is furan insoluble in ether?
Furan is insoluble in ether because furan is a polar compound and ether is a nonpolar solvent. Like dissolves like, so the polarity mismatch between furan and ether prevents them from forming a homogeneous solution.
Why furan do not show nucleophilic subtitution reaction?
Furan does not typically undergo nucleophilic substitution reactions because of its aromatic nature, which offers stability due to delocalization of the pi electrons in the ring. This makes furan less reactive towards nucleophilic attack compared to non-aromatic compounds.

Pyrrol has a lone pair of electrons on the nitrogen atom, which is more available for donation compared to the lone pair on oxygen in furan. This makes pyrrole more basic than furan.
How can you convert furan to pyridine?
Furan can be converted to pyridine through a multi-step process involving the oxidation and cyclization of furan derivatives. One common method is to first convert furan to 2-furylmethanol, followed by oxidation to form 2-furylaldehyde. Subsequently, cyclization can occur through a condensation reaction with ammonia or an amine, leading to the formation of pyridine. Another approach involves the use of a strong acid to facilitate the rearrangement of furan derivatives into pyridine structures.
What is the role of hexose monophosphate shunt?
to produced reducing equivalents NADPH + H+ for Lipid synthesis To generate pentose sugars for nucleotide synthesis
Is furan a polar compound?
Yes, furan is a polar compound due to the presence of polar covalent bonds in the molecule. The oxygen atom in furan is more electronegative than carbon, leading to an uneven distribution of electron density and creating a polar molecule.
Does oil contain pentose?
No, oil does not contain pentose properties. Pentose is a monosaccharide that has 5 different carbon atoms and they are usually organized into 2 different groups.
What is basicity of furan?
furan though has a lone pair of electron which is not delocalised but due to high electronegetivity of oxygen it is not a available for donation hence has weak basic proerty
Why furan is more reactive than pyrrole and thiophene?
Furan is more reactive than Pyrrole because it is less stable as it contains an extra lone pair than that of pyrrole, which is available for attack of an acid, results in the destabilization of the ring.
Does pentose sugar provide atoms in DNA?
Deoxyribose, the "D" of DNA, is indeed a pentose.
What is the basicity of furan?
Furan is a heterocyclic compound that contains one oxygen atom in its five-membered ring structure. It can act as a Lewis base and can donate a lone pair of electrons, making it a weak base. Therefore, furan is considered to be a weakly basic compound.
