Draw all products formed when m-chlorotoluene is treated with KNH2inNH3

Short Answer

Expert verified

Three possible products:

Step by step solution

01

Potassium amide

Potassium amide KNH2 is an inorganic reagent used as a strong base in the nucleophilic substitution of an aromatic ring.

Treatment of aryl halides with a strong base like KNH2in the presence of NH3 produces the reactive intermediate, benzyne.

02

Reaction of aryl halide and potassium amide

The reaction of m-chlorotoluene with KNH2 in the presence of NH3 produces two possible benzyne reactive intermediates.

Benzyne upon further treatment with KNH2in the presence of NH3, produces three possible products.
