In reply to Sanghamitra Sanyal. The difference in acidity between these two compounds would be negligible and nearly indetectible. Within a factor of 10 from each other.

In reply to Vish Gos. 2) Due to polarizability, CH3-O- is more basic than CH3-S-. Sulfur, the bigger atom, can spread out its negative charge better than oxygen. Thus, oxygen is less stable, more densely charged, and desires H+ more.

In reply to Verina. That's an elementary acid-base question which has nothing to do with organic chem.

Which will be more acidic cyclohexanol or 4-methylcyclohexanol? Why? None of the above help!!

This is a great site! I was wondering if you are planning to explain material (or if you already have it up on your site) that cover this question: At what pH is terfenidine (pKa = 8.6) 85% ionized? How should I go about solving and understanding this problem?

Really appreciate your superlative work here, Mr. James.
A few questions:
1) Why does basicity of Nitrogen atom decrease with increasing electronegativity? How does it hamper the electron donation capacity?

2) Why does basicity of anions decreases down the group? (For e.g., CH3-O- is more basic than CH3-S-)

3) Why is N-methtyl-1-methanamine more basic than methoxy methane?

this site is really helpful.. thankyou Mr.James! this is the day i actually understand the reason for acids being strong and weak.. when i went up to my teacher to ask why is HI strong, he simply asked me if i do not know this basic fact also.. today i understood that its not a fact and it has a reason for being strong.. hope my teacher too learns from this site..

In reply to jess. crap. Fixed! thanks for the spot
