<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> How can you convert an unsaturated hydrocarbon to a saturated hydrocarbon?

Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Unsaturated hydrocarbons add hydrogen in presence of Pd/Ni catalyst to give saturated hydrocarbons.

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> ${\text{CH}}_2$=${\text{CH}}_2$ + ${\text{H}}_2$ → ${\text{CH}}_3$-${\text{CH}}_3$
