Question

Identify the product 'B' in the following reaction:

\(CH_3MgBr \xrightarrow{\text{Dry ice, Dry ether}} A \xrightarrow{\text{dil. HCl}, H_2O} B\)

• A. Methanoic acid
• B. Ethanoic acid
• C. Methanol
• D. Ethanol

Hint:

Logic Tip: Reaction with $CO_2$ is a classic chain-lengthening reaction. A Grignard reagent with $n$ carbons will produce a carboxylic acid with $n+1$ carbons. Here, methyl ($1$ carbon) becomes ethanoic acid ($2$ carbons).

Answer 1

The Correct Option is B
