Etard Reaction: Final Product Identification
The Etard reaction is a specific organic reaction used for the controlled oxidation of methyl groups attached to aromatic rings.
Reaction Overview
This reaction converts a methylarene (an aromatic compound with a methyl group, like toluene) into an aromatic aldehyde.
The key reagent used is chromyl chloride ($CrO_2Cl_2$).
Reaction Steps
- A methylarene is treated with chromyl chloride ($CrO_2Cl_2$) in an inert solvent (e.g., $CS_2$ or $CCl_4$).
- An intermediate chromium complex is formed.
- This complex is subsequently hydrolyzed.
Final Product
The hydrolysis step yields the corresponding aromatic aldehyde. For example, toluene reacts to form benzaldehyde.
Therefore, the final product in the Etard reaction is an aromatic aldehyde.
