How do the products differ when ethyl bromide reacts separately with KCN and AgCN?

Solution

KCN is predominantly , ionic and therefore , both C and N atoms is available for the electron donation but the reaction occurs through carbon as C-C bonds are stronger than C- N bond, therefore the attack occurs through the carbon atom of the cyanide group forming alkyl cyanides as the main product.
C₂H₅Br +KCN --> C₂H₅CN +KBr

On the other hand ,AgCN is predominantly covalent in nature and nitrogen is free to donate electron pair forming isocyanides as the main product.
C₂H₅Br + AgCN ---> C₂H₅NC
