Question

Ethyl acetate is obtained when methyl magnesium bromide reacts with

• A. ethyl formate
• B. ethyl chloroformate
• C. acetyl chloride
• D. carbon dioxide

Answer 1

Answer: (B)

Ethyl acetate is obtained when methyl magnesium bromide reacts with ethyl chloroformate.
$C{H}_{3}MgBr+Cl-\stackrel{\underset{||}{O}}{C}-O-C_2{H}_5$
$\to \left[Cl-\underset{\stackrel{|}{C}{H}_3}{\stackrel{\underset{|}{O}MgBr}{C}}-O-C_2{H}_5\right]$
$\to \underset{\text{Ethyl acetate}}{C{H}_3-\stackrel{\underset{||}{O}}{C}-O-C_2{H}_5}+MgBrCl$
