Question

Gatterman reaction is used to convert benzene diazonium chloride to

• A. benzene
• B. nitrobenzene
• C. phenetole
• D. phenol
• E. chlorobenzene

Hint:

The Gatterman reaction is a key synthetic route for halogenating aromatic compounds, particularly useful for chlorination and bromination.

Answer 1

Answer: (E)

Step 1: The Gatterman reaction is a well-known method for introducing a chlorine atom into an aromatic ring. 
Step 2: This reaction involves the use of benzene diazonium chloride, which, under the presence of copper(I) chloride (CuCl) and HCl, forms chlorobenzene. 
Step 3: The reaction proceeds through the replacement of the diazonium group (\(N_2^+\)) by a chlorine atom. 
Step 4: Therefore, benzene diazonium chloride is specifically converted to chlorobenzene in the Gatterman reaction.
