Question

Butanonitrile may be prepared by heating :(a) Propyl alcohol with KCN(b) Butyl alcohol with KCN(c) Butyl chloride with KCN(d) Propyl chloride with KCN

Answer 1

hey mate
answer is option D

Answer 2

Answer:

(d) Propyl chloride with KCN is the correct answer.

Explanation:

Butanonitrile has formula C4H7N.

It is in liquid form and colourless.

It is also called as butyronitrile.

It is miscible with most polar solvents.

Propyl chloride

Propyl chloride has formula C3H7Cl.

It is also colourless compound.

Its IUPAC name is 1-chloro propane.

Pottasium cyanide

Pottasium cyanide has formula KCN.

It is colourless and crystalline.

It looks like sugar.

It is used in industrial activities like electroplating and gold mining, etc.

Propyl chloride when heated with pottasium cyanide butanonitrile will be formed.

C3H7Cl + KCN ====> C4H7NC4H7N + KCl.

This reaction is carried out under heat.
