Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
Aqueous solution of following compounds are electrolyzed. Acetylene gas is obtained from (1) sodium acetate (2) sodium maleate (3) sodium succinate (4) sodium fumarateA) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: C
Solution :
\[\underset{sodium\text{ }maleate}{\mathop{\begin{matrix} H-C-COONa \\ || \\ H-C-COONa \\ \end{matrix}}}\,\xrightarrow{Electrolysis}CH\equiv CH\] \[\underset{sodium\text{ }fumarate}{\mathop{\begin{matrix} \,\,\,\,\,\,\,\,\,\,\,\,\,H-C-COONa \\ || \\ NaOOC-C-H \\ \end{matrix}}}\,\xrightarrow{Elecrolysis}CH\equiv CH\] Sodium acetate upon electrolysis gives methane while sodium succinate gives ethene (ethylene).
