Question

Give one-word ethyne on complete hydrogenation gives.

Answer 1

• Hydrogenation means the addition of hydrogen to unsaturated hydrocarbon gives saturated hydrocarbon.
• Thus complete hydrogenation of ethyne gives ethane.
• $\underset{\mathrm{Ethyne}}{\mathrm{CH}\equiv \mathrm{CH}\left(\mathrm{g}\right)}+\underset{\mathrm{Gas}}{\underset{\mathrm{Hydrogen}}{2{\mathrm{H}}_2}}\stackrel{\mathrm{Ni}\mathrm{catalyst}}{\to }\underset{\mathrm{Ethane}}{{\mathrm{CH}}_3-{\mathrm{CH}}_3\left(\mathrm{g}\right)}$
