A) Esterification
B) Claisen condensation
C) Williamson's synthesis
D) Trans-esterification
Correct Answer: B
Solution :
\[\underset{ethyl\text{ }acetate}{\mathop{C{{H}_{3}}COO{{C}_{2}}{{H}_{5}}}}\,+C{{H}_{3}}-\underset{\begin{smallmatrix} || \\ O \end{smallmatrix}}{\mathop{C}}\,-O{{C}_{2}}{{H}_{5}}\] \[\xrightarrow[or\,Na+{{C}_{2}}{{H}_{5}}OH]{NaN{{H}_{2}}/liquid\text{ }N{{H}_{3}}}\underset{ethyl\text{ }acetoacetate}{\mathop{C{{H}_{3}}-\underset{\begin{smallmatrix} || \\ O \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{2}}-\underset{\begin{smallmatrix} || \\ O \end{smallmatrix}}{\mathop{C}}\,-O{{C}_{2}}{{H}_{5}}}}\,\] \[+{{H}_{2}}O\] This reaction is called Claisen condensation.You need to login to perform this action.
