Strongest nucleophile in polar protic solvent
WebThe picture changes if we switch to a polar aprotic solvent, such as acetone, in which there is a molecular dipole but no hydrogens bound to oxygen or nitrogen. Now, fluoride is the best nucleophile, and iodide the weakest. Relative nucleophilicity in a polar aprotic solvent Web•More polarizable nucleophiles will be less affected by polar protic solvents, since hydrogen bonding ability is greatest for most electronegative nucleophiles. •Polar aprotic solvents will not hydrogen bond: therefore they are good solvents for the S N 2 e.g. HS > HO:PH 3 > :NH 3 I > Br > Cl > F 2. Electronegativity: The less tightly held ...

WebAnd then in this situation, fluoride is actually the best nucleophile, followed by chloride, followed by bromide, followed by iodide. So here, you're going in the direction of basicity. This is the best. This is the worse in an aprotic solvent. If it was in a protic solvent, this is … In a polar aprotic solvent, the cation is preferentially solvated, leaving the … WebA nucleophile can attack a carbocation from either face due to its structure 3 sp2 planar Rank the nucleophiles in order of their nucleophilicity acetone. Order them with the strongest nucleophile on top. H2N (-) HO (-) F (-) Secondary alkyl halides may react by SN1 or SN2 reaction mechanisms.
