The product that is obtained by the reaction of one mole of acetylene with two moles of hydrogen gas in the presence of a platinum catalyst is to be identified. Concept introduction: In the reaction of alkynes with hydrogen gas, the platinum catalyst forms a π- complex with alkyne due to which the addition of hydrogen over double bond takes place. This reaction is termed as hydrogenation reaction of unsaturated hydrocarbons , which is used for their conversion into saturated hydrocarbons.

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 .
