Which of the following gives ethyl alcohol by the action of methyl magnesium hal
Which of the following gives ethyl alcohol by the action of methyl magnesium halide followed by hydrolysis?
- A. Formaldehyde
- B. Acetaldehyde
- C. Acetic acid
- D. Methyl alcohol
Step-by-step solution
Methyl magnesium halide (CH3MgX) reacts with formaldehyde (HCHO) via nucleophilic addition, followed by hydrolysis, to yield ethyl alcohol (CH3CH2OH). Other options give different products: acetaldehyde gives isopropyl alcohol, acetic acid gives a tertiary alcohol, and methyl alcohol reacts with the Grignard reagent to form methane.
