Thiophene is less basic than furan because sulfur is less electronegative than oxygen, making the lone pair on the sulfur less available for donation to a proton. Additionally, the sulfur atom is larger in size compared to oxygen, which makes the lone pair less localized and less available for protonation.
What else can I help you with?
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.
Why thiophene is more aromatic than pyrrole and furan?
Because the electronegativity of oxygen is the highest among others. That is, oxygen doesnt want to share its electron pairs to be delocalized over the molecule. In other words, it is the direct result of electron availability which is the highest in furan.
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 do 5-membered ring aromatic heterocycles pyrrole and furan undergo electrophilic substitution more rapidly than benzene while 6-membered ring heterocycles like pyridine are less reactive than Benz?
pyridine is less reactive than benzene because when we form its conjugate base then it'll b more stable than dat of benzene.. so more stabler means less reactive.......and also due to more resonance in benzene it will b more reactive...same 4 furan and pyrrole
Why pyrrole is less basic than pyridine?
Pyrrole is less basic than pyridine because the lone pair of electrons on the nitrogen in pyrrole is part of the aromatic system and less available for donation compared to the lone pair on the nitrogen in pyridine. This makes pyridine more basic than pyrrole.
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.

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.
Do Furan is weak base Or strong base?
Furan is a weak base. It is a heterocyclic compound that contains oxygen in its ring structure, making it less basic than typical amines due to the lower availability of lone pair electrons for proton donation.
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.
Can you get less than Basic Cable with comcast?
Limited basic.

Why pyrrole is less basic than pyridine?
Pyrrole is less basic than pyridine because the lone pair of electrons on the nitrogen in pyrrole is part of the aromatic system and less available for donation compared to the lone pair on the nitrogen in pyridine. This makes pyridine more basic than pyrrole.
Which is more stable pyrrole or furan?
Pyrrol is most stable because a lone pair on nitrogen is involved in resonance and aromatic character and not available for the attack of an acid but in pyrrol the two electron pairs on oxygen are present one is involved in aromatic character and other is available for the attack of an acid which may break down the ring.
Why para nitro aniline is less basic from aniline?
Because the electron withdrawing resonance efect caused by the nitro group on the structure, it makes the electrons pair on the nitrogen less available, if the electron pair is less available it's less basic
When a solution is basic the pOH is always less thanWhen a solution is basic the pOH is always less than?
When a solution is basic, the pOH is always less than 7. This is because basic solutions have a higher concentration of hydroxide ions (OH⁻), which results in a lower pOH value. In contrast, a neutral solution has a pOH of 7, while acidic solutions have a pOH greater than 7. Therefore, the pOH of basic solutions reflects their higher alkalinity.
A solution whose pH is 9.0?
This would represent a mild base (or basic) solution. Greater than 7.0 = basic. Less than 7.0 = acidic.
