Question

Ethyl acetate is obtained when methyl magnesium iodide reacts with

• A. Ethyl formate
• B. Ethyl chloroformate
• C. Acetyl chloride
• D. Carbon dioxide

Answer 1

Answer: (B)

Ethyl chloroformate

$C{H}_{3}MgI+\underset{\text{Ethyl Chloroformate}}{Cl-\stackrel{\begin{array}{c}O\\ \parallel \end{array}}{C}-O{C}_2{H}_5}\to$ $[Cl-\stackrel{\begin{array}{c}OMgI\\ |\end{array}}{\underset{\begin{array}{c}|\\ C{H}_3\end{array}}{C}}-O{C}_2{H}_5]$

$\to \underset{\text{Ethyl Acetate}}{C{H}_3-\stackrel{\begin{array}{c}O\\ \parallel \end{array}}{C}-O{C}_2{H}_5}+Mg{<}_I^{Br}$
Option B is correct.
