WebSN1 - Solvated Sn1 reactions are more likely to occur in polar, protic solvents due to their ability to stabilize the carbocation charge. Charges are stabilized by prototic solvents, which surround them and interact with them. Protic solvents form hydrogen bonds, though they are stabilized by sn1 reactions mediated by dipole interactions. WebThe solvent in all of the cases shown in Tables 9.4 and 9.5 and Fig. 9.5 is methanol, a protic solvent. In a protic solvent, hydrogen bonding occurs between the protic solvent molecules (as hydrogen bond donors) and the nucleophilic anions (as hydrogen bond acceptors). The strongest Brønsted bases are the best

WebAcetone is an aprotic solvent (Section 10.3) because it does not have hydrogen atoms that can form hydrogen bonds to nucleophiles. The electron pairs of the carbonyl oxygen atom can solvate cations, but not anions. Consequently, anions have greater nucleophilicity in acetone than in protic solvents such as ethanol.
