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. jobs available in eastern cape

WitrynaThe nucleophile will be “solvated” in a sense by the Nitrate ion, stabilizing the nucleophile and lowering the energy of the system. The molecular orbitals drop. The nucleophile is less likely to act as a hard nucleophile, then. HNO3 isn’t likely to form in solution, so of course it won’t deprotonate a stray ethanol. But, there is ... WitrynaAnswer (1 of 2): It is SH which is a better nucleophile, because 1. S is a bigger atom, and therefore its outermost electrons are less bound to the atom and can be more easily shared with another atom in bond forming. 2. Because S is a bigger atom, its surface volume is much bigger. This also he...
