A) Succinic anhydride
B) Acetic acid
C) \[C{{O}_{2}}\] and methane
D) Propionic acid
Correct Answer: A
Solution :
When succinic acid is heated it forms. Succinic anhydride \[\underset{Succinic\ acid}{\mathop{\underset{C{{H}_{2}}COOH}{\mathop{\overset{C{{H}_{2}}COOH}{\mathop{|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,}}\,}}\,}}\,\underset{-{{H}_{2}}O}{\mathop{\xrightarrow{\,\,\Delta \,\,\,}}}\,\underset{Succinic\,anhydride}{\mathop{\overset{C{{H}_{2}}CO}{\mathop{\underset{C{{H}_{2}}CO}{\mathop{|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,}}\,}}\,\ >O}}\,\]
