Covalent bonds are much stronger than hydrogen bonds: the O−H O − H has a strength of 467 kJ/mol, while the hydrogen bond is usually between 4 to 40 kJ/mol. Just want to point out that there is a subtlety to the word "water": I was looking for the pKa p K a of imidazole and found this pKa p K a table [1]: Compound Imidazolium 2-Aminoimidazolium 1-Methyl-2-aminoimidazolium 4,5-Dimethyl-2-aminoimidazolium pKa 7.38 8.46 8.65 9.21 Compound p K a Imidazolium 7.38 2-Aminoimidazolium 8.46 1-Methyl-2-aminoimidazolium 8.65 4,5-Dimethyl-2-aminoimidazolium 9.21.

This would be a strong acid too and the inflection point would be that for water at pH 7. Note that the pKa 1.69 is assuming HX+XX− H X + X X − and is taken at 1/2 of the NaX+OHX− N a X + O H X − used. Knowing that HX2SOX4 H X 2 S O X 4 has two protons, the second pKa should be taken at 150% on the plot which would give the correct pKa ...

Feb 6, 2015 · Some Fortran use is because of performance. The language was designed to be: especially suited to numeric computation and scientific computing. Many times, I find chemistry coders sticking to Fortran because they know it and have existing highly optimized numeric code-bases.

When explained properly, resonance is a consequence of our unability to draw adequate depictions of what the bonding situation in the molecule truly looks like. For example, take a benzene ring. We can only draw single and double bonds. The structures should be identical whether the double bonds are in 1,3,5 or 2,4,6 positions.
