Witryna16 sie 2024 · When the donor atom is same, a general rule applies: nucleophilicity parallels basicity. Thus, comparing the basic strength of methoxide and hydroxide, it is observed that methoxide is a stronger base than hydroxide (as it the conjugate base of a weaker acid i.e. methanol when compared to water). Thus, methoxide is a stronger … Witryna20 lis 2015 · Deciding E1/E2/SN1/SN2 for cyanide ion. Thus, the cyanide ion is a strong base. Also, the cyanide ion is a good nucleophile. So in the reaction of alkyl halides with K C N, a mixture of products must be formed depending on the solvent and alkyl group. However my text suggests that the reaction proceeds only via S N 2.
