Haloalkanes react with KCN to form alkyl cyanides as main product while AgCN forms isocyanides as the chief product. Explain. |
| Answer» Solution :KCN is predominantly IONIC and provides cyanide ions in solution. Although both carbon and nitrogen atoms are in a position to donate electron pairs, the attack TAKES place mainly through carbon atom and not through nitrogen atom since C - C BOND is more STABLE than C - N bond. However, AgCN is mainly covalent in NATURE and nitrogen is free to donate electron pair forming isocyanide as the main product. | |
