Vedclass · Answer

(D) The reaction proceeds as follows:$1$. Cyclopropyl bromide reacts with $Mg$ in the presence of $Et_2O$ to form the Grignard reagent,cyclopropylmagnesium bromide $(C_3H_5MgBr)$.$2$. The Grignard reagent then undergoes a nucleophilic addition reaction with $CO_2$ to form the magnesium salt of the carboxylic acid,which is cyclopropylmagnesium carboxylate.$3$. Finally,acid hydrolysis with $H_3O^+$ converts the magnesium salt into the final product,cyclopropanecarboxylic acid $(C_3H_5COOH)$.

What is $A$ in the following reaction?
$Cyclopropyl bromide \xrightarrow[(ii) CO_2, (iii) H_3O^+]{(i) Mg, Et_2O} A$
