The reason as to how the color of β -carotene be affected by treatment with a large excess of H 2 over a Pt / C catalyst is to be explained. Concept introduction: The addition of H 2 in presence of a catalyst is known as catalytic hydrogenation reaction. This is a syn addition. The alkene is reduced to an alkane . In this reaction, the weak π bond of alkene and sigma bond between H 2 is broken and two C − H bonds are formed.
