WebThe iodide ion has a negative charge, so it is attracted to the partial positive charge on the methyl carbon. It is a strong nucleophile because of its polarizability. HI is a strong acid, … WebWeak nucleophiles and weak electrophiles are not likely to react at all; the frontier orbital gap is too wide in this case. A weak electrophile is likely to react only if it encounters a strong nucleophile; a weak nucleophile is likely to react only if it encounters a strong electrophile. Given the HOMO energy level of Nu as indicated:
WebJun 2, 2015 · The key factors that determine the nucleophile's strength are charge, electronegativity, steric hindrance, and nature of the solvent. Charge Nucleophilicity increases as the density of negative charge increases. An anion is always a better nucleophile than a neutral molecule, so the conjugate base is always a better nucleophile. … WebMay 28, 2024 · We can see that the pKa of methanol ( C H X 3 O H) is 16 and the pKa of cyanide ( C N) is 9.1 therefore the methanol is going to be a better nucleophile since it is …
