Answer 2

Answer:

The Correct Answer would be in the presence of Potassium Cyanide(KCN) and aqueous ethanol. Ethyl Bromide (CH₃–CH₂–Br), in the presence of alcoholic KCN gives Propane Nitrile (CH₃–CH₂–CN).

Explanation:

Ethyl Bromide or Bromoethane is an alkylating agent which is commonly used as a chemical intermediate in numerous organic processes. It appears as colorless volatile liquid, is denser than water and is basically slightly soluble in water.

For converting it into Propane Nitrile, bromoethane or ethyl bromide is subjected to a catalyst, which is commonly known as KCN, in the presence of aqueous ethanol.

Reaction :

                                          (in presence of alc. KCN)

                   CH₃–CH₂–Br                  ⇒                        CH₃–CH₂–CN

                 (Bromoethane)                                          (Propane Nitrile)
