In the given reaction, X is \[C{{H}_{3}}CHO+C{{H}_{2}}{{(COOH)}_{2}}\xrightarrow[heat]{Pyridine}X\]

A)  \[C{{H}_{3}}COOH\]

B)  \[{{C}_{2}}{{H}_{5}}COOH\]

C)  \[C{{H}_{3}}CH=CH.COOH\]

D)  \[HOOC.CH=CH.COOH\]

Correct Answer: C

Solution :

\[C{{H}_{2}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,H+C{{H}_{2}}{{(COOH)}_{2}}\xrightarrow[\Delta ]{Pyridine}\]
