Detailed Solution

Tollen's reagent is used to detect the presence of aldehydes and alpha-hydroxy ketones.
The reagent is a solution of silver nitrate in aqueous ammonia, which oxidizes the aldehydes to carboxylic acids and reduces the silver ions to metallic silver.
Benzene does not contain an acidic hydrogen atom that can be oxidized by Tollen's reagent to produce a carboxylic acid, which is required to form a white precipitate of silver carboxylate.
Therefore, it does not give a white precipitate with Tollen's reagent.
