We know that when RX forms RCN as major product in presence of alcoholic KCN, where R is an alkyl group.What amazes me is that the same does not apply to alcoholic AgCN.My question is :why does RX+
alc. AgCN produce RNC as major organic product and not RCN?

Thank you.

Hint 1: The Ag⁺ interacts with RX before cyanide attacks.
