Step 2
In this structure, the negative charge (-) is located on the oxygen atom, representing the carboxylate ion.
Explanation:
The reaction with Tollens reagent oxidizes the aldehyde group (-CHO) to a carboxylate group (-COO-) and results in the formation of this organic anion.

Answer
When 3-methylbenzaldehyde reacts with Tollens reagent, it undergoes oxidation, transforming the aldehyde group (-CHO) into a carboxylate ion (-COO-). The resulting organic anion is 3-methylbenzoate, with a structural formula showing the carboxylate group (-COO-) attached to the benzene ring. This reaction is a classic test for the presence of aldehydes and is characterized by the conversion of the aldehyde functional group into a carboxylate group in the organic compound.

Understanding the Components
Before probing into the response medium, let’s familiarize ourselves with the crucial factors involved
- 3- Methylbenzaldehyde Also known as meta- tolualdehyde, this sweet aldehyde contains a methyl group(- CH3) attached to the benzene ring.
- Tollens Reagent Named after the druggist Bernhard Tollens, Tollens reagent is a result of tableware nitrate( AgNO3) and waterless ammonia( NH3). It’s generally used to distinguish between aldehydes and ketones grounded on their capability to suffer oxidation.
The Reaction Process
When 3- methylbenzaldehyde reacts with Tollens reagent, it undergoes oxidation to form an organic anion. The detailed response medium involves the transfer of electrons and the conformation of intermediate species. Tollens reagent oxidizes the aldehyde functional group(- CHO) to a carboxylate anion(- Susurrus-) while reducing tableware ions( Ag) to form a tableware glass.
Structural Formula of the Organic Anion
To fantasize the structural formula of the organic anion formed in this response, we need to consider the molecular structure of 3- methylbenzaldehyde and the chemical changes it undergoes. By removing the hydrogen snippet from the aldehyde group and incorporating the carboxylate group, we can depict the performing organic anion. The charge on the ion should also be indicated to directly represent its ionic nature.
Significance of Tollens Reagent
Tollens reagent serves as a precious tool in organic chemistry for distinguishing between aldehydes and ketones. The conformation of a tableware glass upon response with an aldehyde is a characteristic test for the presence of aldehydes, as ketones don’t suffer oxidation under these conditions. also, Tollens reagent provides a mild and picky system for oxidizing aldehydes without affecting other functional groups.
Conclusion
The response between 3- methylbenzaldehyde and Tollens reagent exemplifies the transformative power of chemical responses in organic conflation. By imaging the structural formula of the organic anion formed, we gain perceptivity into the molecular changes that do during oxidation. Tollens reagent, with its unique capability to widely oxidize aldehydes, holds significant significance in laboratory analysis and organic chemistry operations. Through continued disquisition and understanding of chemical responses, we uncover new pathways for molecular design and conflation, driving advancements in the field of organic chemistry.
