Can Gattermann-Koch reaction be considered similar to Friedel Craft's acylation ? Discuss.

Explanation

To determine whether the Gattermann-Koch reaction can be considered similar to Friedel-Crafts acylation, we need to analyze both reactions in terms of their mechanisms, reactants, and products.

### Step 1: Understanding the Gattermann-Koch Reaction
The Gattermann-Koch reaction involves the reaction of benzene with carbon monoxide (CO) and hydrochloric acid (HCl) in the presence of anhydrous aluminum chloride (AlCl3). The primary product of this reaction is benzaldehyde (C6H5CHO).

- **Mechanism**:
1. Benzene reacts with CO and HCl, where HCl dissociates into H+ and Cl-.
2. The H+ ion interacts with the carbon monoxide, leading to the formation of a carbonyl cation (C=O with a positive charge).
