The carbide/s that is/are hydrolysed to produce acetylene gas is/are\

Question

Professor PC Thomas Classes · Answer

$\mathrm{Cu}_{2} \mathrm{C}_{2}$ and $\mathrm{Ag}_{2} \mathrm{C}_{2}$ are not true acetylides because these on hydrolysis do not produce acetylene. SiC does not undergo hydrolysis. $\mathrm{CaC}_{2}+2 \mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{C}_{2} \mathrm{H}_{2}+\mathrm{Ca}(\mathrm{OH})_{2}$
