Question

how do alkyl halides react with alcholic KCN alcholic Agcl​

Answer 1

HEY MATE----

HERE IS YOUR ANSWER

Alkyl halides react with alcoholic KCN (potassium cyanide) to form alkyl cyanides (alkanenitriles). The reaction of alkyl halides with potassium cyanide is very useful when we want to increase the length of the carbon chain. For example, CH3CH2I contains two carbon atoms while CH3CH2CN contains three carbon atoms.

Answer 2

Answer:

Aqueous KOH is alkaline in nature i.e. it dissociates to produce a hydroxide ion. These hydroxide ions act as a strong nucleophile and replace the halogen atom in an alkyl halide. This results in the formation of alcohol molecules and the reaction is known as nucleophilic substitution reaction.
