WebScience Chemistry Explain using examples how electronic factors (resonance and inductive effects) can be used to determine acidity and basicity of organic compounds. Use electronic and stability factors to account for the acidity of each highlighted hydrogen in the molecule below. Identify the most acidic proton. WebIn aprotic solvents, there are no protons to block or "solvate" the nucleophile. As a result, the anion that has more electron density is more nucleophilic. Since fluorine is more electronegative than iodine, the fluoride anion is more electron dense than iodide. In aprotic solvents, nucleophilicity correlates to basicity.

WebThe dividing line is four carbons. Methanol, ethanol, and propan-1-ol are infinitely soluble in water. Butan-1-ol is partially soluble at 9 g/100 mL. The solubility of pentan-1-ol is 2.7 g/100 mL. Many people call this "insoluble". The solubility of octan-1-ol is 0.054 g/100 mL. That's definitely insoluble!
