Question 9

Why does haloalkanes react with KCN to form Cyanide and AgCN to form Cyanide?

Answer 9

KCN is predominantly Ionic and released CN - ions in solution eventhough both carbon and nitrogen are in place to donate e, then donation mainly happens through C because C-C bond is stronger than C-N bond. In the case of AgCN its covalent so nitrogen is free to donate electrons and forms isocyanides
