A) Tartaric acid, propanoic acid
B) Succinic acid, succinic anhydride
C) Maleic anhydride, maleic acid
D) Methyl malonic acid, propanoic acid
Correct Answer: D
Solution :
\[\underset{A}{\mathop{{{C}_{4}}{{H}_{6}}{{O}_{4}}}}\,\xrightarrow{\Delta }\underset{B}{\mathop{{{C}_{3}}{{H}_{6}}{{O}_{2}}}}\,\] From above equation, it is clear that \[C{{O}_{2}}\] is lost due to heating. Thus, A is a dibasic acid with two -COOH groups on same carbon atom (gem position). Thus, A isYou need to login to perform this action.
