Read the passage given below and answer the following questions:
Aldehydes, ketones and carboxylic acids are few of the major classes of organic compounds containing carbonyl groups. Aldehydes are prepared by dehydrogenation or controlled oxidation of primary alcohols and controlled or selective reduction of acyl halides. Ketones are prepared by oxidation of secondary alcohols and hydration of alkynes. Carboxylic acids are prepared by the oxidation of primary alcohols, aldehydes and alkenes by hydrolysis of nitriles and by treatment of Grignard reagents with carbon dioxide.
Q. The reagent which does not react with both, acetone and benzaldehyde.
- a)Sodium hydrogensulphite
- b)Phenyl hydrazine
- c)Fehlings’ solution
- d)Grignard reagent

Reactivity of Acetone and Benzaldehyde:
Acetone and benzaldehyde are both examples of carbonyl compounds, specifically ketones and aldehydes, respectively. In the given options, we need to identify the reagent that does not react with both acetone and benzaldehyde.
Fehling's Solution:
Fehling's solution is a commonly used reagent for the detection of reducing sugars, particularly aldehydes. It consists of two separate solutions - Fehling's A (copper(II) sulfate solution) and Fehling's B (alkaline sodium potassium tartrate solution). When a reducing sugar, such as glucose, reacts with Fehling's solution, a red precipitate of copper(I) oxide is formed.
Explanation:
Fehling's solution is not suitable for the detection of ketones like acetone because ketones do not have a free aldehyde group. Therefore, they do not react with Fehling's solution to form a red precipitate. Instead, ketones undergo oxidation reactions to form secondary alcohols.
On the other hand, benzaldehyde is an aldehyde and does contain a free aldehyde group. It can react with Fehling's solution to form a red precipitate of copper(I) oxide. Therefore, the correct answer is option C - Fehling's solution.
Summary:
- Acetone is a ketone and does not react with Fehling's solution.
- Benzaldehyde is an aldehyde and reacts with Fehling's solution to form a red precipitate of copper(I) oxide.
- Fehling's solution is used to detect reducing sugars, particularly aldehydes, but not ketones like acetone.
