Question

c2h5br gives differnt products with kcn(alc.) and kcn(alc) why​

Answer 1

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.
