Which of the following compounds will react with methyl magnesium Iodide followed by acid hydrolysis to give ethyl alcohol?
Correct answer: D. Formaldehyde
- A. Ethylene
- B. Acetone
- C. Acetaldehyde
- D. Formaldehyde
Explanation
When formaldehyde (CH2O) reacts with methyl magnesium iodide (CH3MgI), followed by acid hydrolysis, it gives ethyl alcohol (ethanol). The Grignard reagent reacts with the formaldehyde carbonyl group, forming a compound that can be hydrolyzed to yield ethyl alcohol.The reaction can be represented as follows:CH2O + CH3MgI → CH3CH2OH

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
