The reaction of 1-iodopropane with potassium thiocyanate (KSCN) in certain solvents results in the formation of two isomeric products, propylthiocyanate and propylisothiocyanate (see scheme below), via the SN2 reaction mechanism. Attempts to prepare a similar mixture of these same isomeric products (propylthiocyanate and propylisothiocyanate) starting from 1-propene is illustrated below. Despite the strong acidity of thiocyanic acid (recall pKa = 1.1), this addition reaction does not lead to either of the products indicated. Based on your knowledge of alkene addition reactions, explain this experimental result.
