Question

Conversion of ethene to ethane is an example of _____

Answer 1

Conversion of Ethene ($C_2{H}_4$) to ethane is an example of Addition of hydrogen ($H_2$) or hydrogenation.

When Hydrogen ($H_2$) is added to Ethene ($C_2{H}_4$) , in the presence of Nickel ($Ni$) or Platinum ($Pt$) or Palladium ($Pd$) as catalyst at $200°C-300°C$, Ethane ($C_2{H}_6$) is formed.

$\underset{\mathrm{Ethene}}{{\mathrm{CH}}_2={\mathrm{CH}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Ethane}}{{\mathrm{CH}}_3-{\mathrm{CH}}_3\left(\mathrm{g}\right)}$

Thus, conversion of Ethene ($C_2{H}_4$) to ethane is an example of Addition of Hydrogen ($H_2$) or hydrogenation.
