On heating an aliphatic primary amine with chloroform and ethanolic potassium hydroxide, the organic compound formed is:

1. an alkane diol
2. an alkyl cyanide
3. an alkyl isocyanide
4. an alkanol

Correct answer: an alkyl isocyanide

Solution

Heating an aliphatic primary amine with chloroform and ethanolic potassium hydroxide leads to the formation of an alkyl isocyanide through the formation of an isocyanide functional group, which is characteristic of this reaction.
