A neutral organic compound with four carbon atoms $\mathrm{X}$ reacts with sodium metal to evolve a gas which burns with a ‘pop’ sound. Another organic compound $\mathrm{Y}$ with four carbon atoms reacts with sodium hydrogen carbonate to evolve a gas which turns lime water milky. When compounds $\mathrm{X}$ and $\mathrm{Y}$ are heated together in the presence of a little of concentrated sulphuric acid, then a new compound $\mathrm{Z}$ is formed.
