Alkyl halide is converted into alkyl isocyanide by reaction with

Options

  1. ANaCN
  2. BNH 4 CN
  3. CKCN
  4. DAgCN

Correct answer

D. AgCN

Step-by-step solution

AgCN is covalent in nature so it does not dissociate in to Ag + and CN - and on nitrogen electron density is high,and nitrogen is free to donate electron pair forming isocyanide or alkyl isonitrile as the main product. R - X + AgCN → RNC + AgX KCN is ionic in nature, so it dissociates completely. R - X + KCN → RCN + KX Hence the answer is D.
