What is Tollen’s reagent for Class 12?
> Tollen’s reagent consists of a solution of silver nitrate and ammonia; and is named after Bernhard Tollens, a German chemist. Hence Tollen’s reagent is an ammoniacal solution of silver nitrate ([Ag(NH3)2]+(aq)).
What is Tollen’s reagent Class 11?
Tollens’ reagent is a chemical reagent used to determine the presence of an aldehyde, aromatic aldehyde and alpha-hydroxy ketone functional groups. The reagent consists of a solution of silver nitrate and ammonia.
What is Tollen’s reagent how it is prepared?
In order to prepare Tollens’ reagent, Sodium hydroxide is added to a solution of silver nitrate dropwise until a light brown precipitate is obtained. To this, concentrated ammonia solution is added dropwise until the brown precipitate of Ag2O dissolves completely.
What is Tollen’s reagent shaala com?
Tollens’ test uses a reagent known as Tollens’ reagent, which is a colorless, basic, aqueous solution containing silver ions coordinated to ammonia [Ag(NH3)2+]. Step 1: Aqueous silver nitrate is mixed with aqueous sodium hydroxide.
What is Tollen’s reagent write its reaction with acetaldehyde?
– Tollens reagent is a solution of silver nitrate and ammonia. – Acetaldehyde when reacted with tollens test it gets oxidized to acetic acid.
What is Tollen’s reagent write one usefulness of this reagent?
Ammoniacal silver nitrate solution is called Tollens’ reagent. It is used to test aldehydes. Both aliphatic and aromatic aldehydes reduce tollen’s reagent to shining silver mirror. It is also used to distinguish aldehydes from ketones.

Tollen’s reagent is an ammonical silver nitrate solution. Tollen’s reagent is used to test an aldehyde. Both aliphatic and aromatic addehydes reduce Tollen’s reagent .
Do alcohols give Tollens test?
No bro, only Aldehydes give s Tollens test. It is often said that Tollens’ reagent does not react with alcohols. However, from personal experience, gentle heating of a primary alcohol with Tollens’ will cause a small amount of oxidation and result in a fine black precipitate
