Answer :
Final answer:
Among the given options, Schiff's, Fehling's, and Tollen's reagents can all react with aldehydes and ketones; these are commonly used as chemical tests for these groups. The Grignard reagent can also react with them but is mainly used for synthesis reactions.
Explanation:
In an organic chemistry context, it's important to know which reagents will react with certain functional groups. Aldehydes and ketones are two such groups. Among the choices that you've listed, Schiff's reagent, Fehling's reagent, and Tollen's reagent are all capable of reacting with aldehydes and ketones.
Each of these reagents are used as chemical tests. Fehling's and Tollen's reagents both test for the presence of aldehydes, with Fehling's resulting in a red precipitate and Tollen's in a silver mirror if aldehydes are present. Schiff's reagent also reacts with aldehydes, turning a pink color upon reaction.
The Grignard reagent, while also used in reactions with aldehydes and ketones, primarily adds to the carbonyl group, forming alcohols. It doesn't act as a test for these groups, but is rather used as a tool in synthesis reactions.
