With the help of an example, explain the process of hydrogenation. Mention the essential conditions for the reaction and state the change in physical property with the formation of the product.

Answer:

\[{{H}_{2}}C=C{{H}_{2}}+{{H}_{2}}\xrightarrow{Ni/Pt}{{H}_{3}}C-C{{H}_{3}}\]

Or

\[Vegetable oil + {{H}_{2}}\xrightarrow{Ni/pt} Vanaspati ghee\]

Essential condition for hydrogenation is the presence of a catalyst like Ni, Pt or Pd Change observed in the physical property during hydrogenation is the change of the unsaturated compound from the liquid state to the corresponding saturated compound in the solid state.
