Which of the following reagents reacts with both aldehydes and ketones?
Options
- AGrignard Reagent
- BSchiff's reagent
- CTollen's reagent
- DFehling's Solution
Correct answer
A. Grignard Reagent
Step-by-step solution
Grignard reagent ( RMgX ) reacts with both aldehydes and ketones to form addition products, which upon hydrolysis yield alcohols. Formaldehyde gives primary alcohols, other aldehydes give secondary alcohols, and ketones give tertiary alcohols. Schiff's reagent, Tollen's reagent, and Fehling's solution are mild oxidizing agents. They selectively oxidize aldehydes but do not react with ketones. Answer: Grignard Reagent
