Given acetic acid:

CH3COOH{: } H-C<|H><`|H>-C<`||O>-O-H

Which H's are acid at the acetic acid: those who H’s at the same time, carbon or the H at the same time, oxygen?

Solution:

A connection can several H-atoms contain, z.B. Acetic acid, CH₃COOH. The at the C-atom of which: H's are less very strong polarized as the H, which at the O-atom binded is. Reason: Differences in electronegativity: C and H have similar EN values and thus have similar partial positive or negative charges. However, O and H have very different EN values, with H clearly positively partially charged, as opposed to the negatively partially charged O atom. The splitting of a H⁺ (please note:: no partly loaded but a complete [translation unavailable] loading or The failure of a complete negative loaded electrons) is thus through this large EN-difference eased. (note for the specialists: yes, I [translation unavailable], HF power difficulties, leads but at this place to far away)
