Is kcn basic or acidic
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. WitrynaFor example, potassium cyanide (KCN) is prepared from a strong base (KOH) and weak acid (HCN), and therefore, its aqueous solution will be basic. You can also write the reaction if in doubt: KOH + HCN → KCN + H 2 O So, we have a shortcut to determine if the solution will be basic or acidic, but how does that work?
