Hello,
We can approach an answer to this question by doing the resonance forms of both compounds,,, and we can then conclude that the lone pair found in pyrrole ( 5-membered ring ) is involved in the five resonance forms while on the other hand the lone pair found in the pyridine ( 6-membered ring ) is NOT involved in the two resonance forms and this leads to form a concentrated charge in case of pyridine.
SO,,, pyrrole has the lone pair totally involved in the resonance and this means that there is not concentrated charge on the (N) which makes pyrrole a weaker bas than the Pyridine.
Hope The Answer Was brief and Helpful

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.
What are the key differences between pyrrole and pyridine in terms of their chemical structures and properties?
Pyrrole and pyridine are both aromatic compounds, but they differ in their chemical structures and properties. Pyrrole has a five-membered ring with four carbon atoms and one nitrogen atom, while pyridine has a six-membered ring with five carbon atoms and one nitrogen atom. Pyrrole is more reactive due to its higher electron density, while pyridine is less reactive and more stable. Pyrrole is a stronger base than pyridine because its nitrogen atom is more basic. Additionally, pyrrole is more acidic than pyridine because its nitrogen atom can donate a proton more easily.
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 more acidic and less basic than pyrrolidine?
Pyrrole C4H4NH (in which N contributes a lone pair) has a pKa - 3.8, but Pyridine (where N is part of the ring's double bond) has a pKa 5.14. Electron pair availability indicates the strength of basicity. In this case, pyridine is the stronger base.
Acdity of pyrrole?
Pyrrole is a weak acid due to the presence of a lone pair on the nitrogen atom that can donate a proton. However, it is generally less acidic than alcohols or carboxylic acids. Its conjugate base, the pyrrole anion, is stabilized by aromaticity.

Is C6H7N strong base?
No, all isomers of this formula are neutral alcohols not the base.
Is NH4OH the weakest base?
No, water is weaker than it.
Which is more basic pyridine or pyrrolidine?
Pyridine is more basic than pyrrolidine. This is because pyridine has a lone pair of electrons on the nitrogen atom in the aromatic ring, which is more available for donation to accept a proton and act as a base compared to pyrrolidine, which has one of its nitrogen lone pairs delocalized in the aromatic ring.
Why aniline is weaker base than methylamine?
Since tha pka of the aniline ion is equal to 4.6, the anilinium ion is a stronger acid than the methylaminium ion, and aniline (c6h5nh2) is a weaker base than methylamine (ch3nh2).
Why pyridine is less basic than piperidine?
Pyridine is less basic than piperidine because the nitrogen in pyridine is part of an aromatic ring, which delocalizes the lone pair of electrons on the nitrogen atom and makes it less available for proton donation. In contrast, piperidine has a more localized lone pair on the nitrogen atom, making it more readily available for proton donation, thus making piperidine a stronger base than pyridine.
Is sodium hydrogen carbonate a weaker base than sodium carbonate?
Yes: hydrogen carbonate is a stronger acid, and therefore a weaker base, than carbonate.
Which is a stronger base Cl- or F-?
F is the stronger base because it is bigger than Cl
