The stereochemistry behind the products formed during catalytic hydrogenation of alkene is to be explained. Concept introduction: Hydrogenation with platinum as a catalyst is used to convert unsaturated hydrocarbons to saturated hydrocarbons. Catalytic hydrogenation can achieve selective hydrogenations like hydrogenation of less substituted and sterically less hindered double bonds.

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .
