Question

reaction between potassium cyanide and 1-chloropropane

Answer 1

Hi dear 

K - C ≡ N + Cl-CH₂-CH₂-CH₃ → CH₃-CH₂-CH₂-CN + KCl 

Answer 2

Answer: The product formed will be butanenitrile.

Explanation:

Reaction of 1-chloropronane with aqueous alcoholic solution of potassium cyanide results in the formation of butanenitrile of 1-cyanobutane. The reaction occurs through $S_N2$ mechanism. The nucleophile here, is cyanide and reacts the carbon which is attached to chlorine atom.

The equation for the above reaction is given below in the image.
