Determining most basic organic chemistry
WebThe value of the equilibrium constant is given by. Kb = [BH+][OH−] B. The greater the value of Kb, the stronger the base. For most weak acids, Kb ranges from 10−2 to 10−13. pKb = − logKb. For most weak acids, pKa ranges from 2 to 13. The smaller the value of pKb , the stronger the base. Here's a video on pKa and pKb.

WebDec 1, 2024 · In Organic Chemistry, acids and bases is really quite qualitative. We’re often looking at whether a compound is even acidic or basic at all.

Knowledge of these … WebWe can identify a potentially acidic H + because it will be bonded to a more electronegative atom; the result is that the electron density in the bond will lie mainly with the more electronegative atom (e.g. O, N, or Cl).The outcome is that, for example, an H–O bond will be weakened (require less energy to break); the H will have a large partial positive …
WebIn ethyl chloride, the Cl atom is the most electronegative atom. It pulls electron density from the C atom, so it becomes δ⁻ and the C atom becomes δ⁺. Ethanol is a nucleophile (N) … WebYes, the more stable the conjugate base (A-), the more reactive the acid will be, thereby favoring dissociation. HA ----> H+ + A-. I'm not a fan of using the electronegativity as an example of acidity, as it has more do with the negative charge distribution among the overall size of the anion once the hydrogen dissociates.
