The Gattermann Koch Synthesis is,
All the above statements are true except statement III. This reaction is electrophilic substitution instead of nucleophilic substitution and HOC+ ion is used as electrophile. Hence, this is the correct answer.

Which of the following statement(s) is true about Gattermann Koch Synt...
Overview of Gattermann Koch Synthesis:
The Gattermann Koch Synthesis is a method used to synthesize aldehydes from aromatic compounds. It involves the reaction of benzene with carbon monoxide in the presence of a Lewis acid catalyst to form an aryl aldehyde.
True Statements:
I. One of the outputs is benzaldehyde:
- The main product obtained from the Gattermann Koch Synthesis is benzaldehyde, which is an aromatic aldehyde. This compound is important in organic synthesis and has various industrial applications.
II. To use formyl chloride, carbon monooxide is combined with hydrochloric acid:
- In the Gattermann Koch Synthesis, formyl chloride (also known as chloroformyl chloride) is used as a source of the formyl group. This compound is generated by combining carbon monoxide with hydrochloric acid. The formyl chloride then reacts with the aromatic compound to form the desired aldehyde.
III. The reaction is a nucleophilic substitution reaction:
- The Gattermann Koch Synthesis does not involve a nucleophilic substitution reaction. Instead, it proceeds through an electrophilic aromatic substitution mechanism, where the electrophilic formyl group is added to the aromatic ring to form the aldehyde product.
Therefore, the correct statement about the Gattermann Koch Synthesis is option 'C' - I and II only.
