Difference between Cyanides and Isocyanides
- Alkyl cyanides have pleasant smell but isocyanides have highly unpleasant odour.
- Alkyl cyanides have lower dipole moment than isocyanides.

- Alkyl cyanide undergoes both acidic and alkaline hydrolysis while alkyl isocyanide undergoes only acidic hydrolysis because negatively charged carbon atom repel OH– ion of the base.
- Reduction
