Question

Identify A and B respectively in the following conversion.

\[\ce{Ethene ->[A] Bromoethane ->[B][\Delta] Ethyl propionate}\]

Options

• HBr, C₂H₅ONa

• Br₂/AlBr₃, C₂H₅COOAg

• HBr, C₂H₅COOAg

• Br₂/AlBr₃, C₂H₅ONa

Answer 1

HBr, C₂H₅COOAg

Explanation:

\[\begin{array}{cc}
\phantom{..............................}\ce{O}\\
\phantom{..............................}||\\
\ce{\underset{Ethene}{H2C = CH2} ->[HBr] \underset{Bromoethane}{H3C - CH2 - Br} ->[C2H5COOAg][\Delta] \underset{Ethyl propionate}{C2H5C - OCH2CH3} + AgBr} 
\end{array}\]
