Question

RX when treated with KCN gives RCN whereas with AgCN gives RNC. why?​

Answer 1

Answer:

Haloalkanes react with KCN to give alkyl cyanide as main product while with AGCN they form Isocyanide as main product give reason

i) Haloalkanes react with KCN to form alkyl cyanides as main product while AgCN forms isocyanide as the chief products. ii) Alcohols do not react with NaBr, but when H2SO4 is added, they form alkyl bromides. Answer: i) KCN is predominantly ionic and provides cyanide ions in solution.
