In pyridine molecule the Nitrogen atom is involved in Aromatic character of ring if lone pair of nitrogen forms a sigma bond with hydrogen the Aromatic ring (Aromaticity) becomes lass stable so pyridine do not accept the proton easily while Aromaticity is not involved in pi-pyridine so its nitrogen atom easily donates the electron pair to a proton .

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.
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
Pyrrole is weaker base than pyridine?
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 ALKASED
How do you determine if an compound is acidic or basic?
Acids have a pH of less than 7 and bases have a pH greater than 7
Is physiological pH about 7.4?
No, such a pH is basic as it is greater than 7. An acidic pH is less than 7.

Can you get less than Basic Cable with comcast?
Limited basic.

Is a pH of 8 more basic or less than a pH of 6?
The higher the pH, the more basic, so a pH of 8 is more basic than a pH of 6.
Synthesis of propylpyrdine?
The synthesis of the propyl pyridine is done using 2-propanol other than the zeolites.
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.
What is more than 2 and less than 3?
In a basic sense, anywhere between 2.01 and 2.99.

The pH of acids and bases?
7.0 is neutral. Less than 7.0 is acidic. More than 7.0 is basic/alkaline.
Is physiological pH about 7.4?
No, such a pH is basic as it is greater than 7. An acidic pH is less than 7.
How do you determine if an compound is acidic or basic?
Acids have a pH of less than 7 and bases have a pH greater than 7
Where would Ajax be on the pH scale?
Ajax is slightly basic with a pH of less than 7.
