Answer:
To determine which compounds will give a secondary alcohol upon reaction with Grignard reagent followed by acid hydrolysis, we need to understand the reaction mechanism and the properties of the compounds involved.
Grignard reagents are organometallic compounds formed by the reaction of an alkyl or aryl halide with magnesium metal. They are highly reactive nucleophiles and can add to a wide range of electrophiles.
When a Grignard reagent reacts with a carbonyl compound, such as an aldehyde or a ketone, the resulting product is an alcohol. The carbon atom of the carbonyl group becomes the new carbon atom in the alcohol, and the oxygen atom of the carbonyl group is replaced by a magnesium halide.
In the case of aldehydes, the product formed is a primary alcohol. In the case of ketones, the product formed is a secondary alcohol.
Now let's analyze the given compounds:
I. HCHO (Formaldehyde)
- Formaldehyde is an aldehyde, and when reacted with a Grignard reagent, it will form a primary alcohol. Therefore, it will not give a secondary alcohol.
II. C2H5CHO (Acetaldehyde)
- Acetaldehyde is also an aldehyde, and it will form a primary alcohol upon reaction with a Grignard reagent. Therefore, it will not give a secondary alcohol.
III. CH3COCH3 (Acetone)
- Acetone is a ketone, and when reacted with a Grignard reagent, it will form a secondary alcohol. Therefore, it will give a secondary alcohol.
IV. RCOOC2H5 (Ester)
- Esters are not reactive towards Grignard reagents. They do not undergo nucleophilic addition reactions with Grignard reagents. Therefore, they will not give any alcohol upon reaction with a Grignard reagent.
Based on the analysis, the correct answer is (2) Only III - CH3COCH3 (Acetone). It will give a secondary alcohol upon reaction with a Grignard reagent followed by acid hydrolysis.
