• What Is Tollens Test?

  Tollens test is generally given by compounds having aldehydic group (aldehydes,alpha-hydroxy ketones and formic acid-its -COOH behaves like a aldehydic group). It gives a white ppt of Silver (where the silver salt is reduced to silver metal and the aldehyde is oxidised to silver salt of carboxylic acid.

• Tollens Reagent

  Tollens Reagent refers to the chemical reagent which is used in the detection of an aldehyde functional group, an aromatic aldehyde functional group, or an alpha hydroxy ketone functional group in a given test substance. The Tollens Reagent is named after Bernhard Tollens, A German chemist who discovered this reagent and its uses. Tollens reagent i...

• Alpha Hydroxy Ketone Tollens Test

  Alpha hydroxy ketones are able to give a positive Tollens’ test since ?-hydroxy ketones have the ability to tautomerize to aldehydes, and the aldehyde gives the Tollens’ test. An ?-hydroxy ketone that cannot tautomerize to a aldehyde won’t give a positive Tollens’ test, like benzoin.

• Tollens Reagent Preparation

  Since Tollens Reagent has a relatively short shelf life, the reagent is not commercially sold. Therefore, this reagent is often prepared directly in the laboratory. One such method for the preparation of Tollens Reagent is described below:
