Question

Which of the following compounds will react with methylmagnesium iodide followed by acid-hydrolysis to give ethyl alcohol?
Options
A Ethylene
B Acetaldehyde
C Formaldehyde
Correct Answer
D Acetone
Correct Answer

Option C is the correct answer.

Detailed Explanation

Methylmagnesium iodide (CH3MgI) reacts with formaldehyde (HCHO) to give ethanol (CH3CH2OH) after acid hydrolysis. Formaldehyde + CH3MgI → CH3CH2OH. Acetaldehyde would give 2-propanol, and acetone would give tert-butyl alcohol.

Hint

Which carbonyl compound with CH3MgI gives ethanol?
