Each of the given alkene is to be matched with its correct heat of hydrogenation. Concept introduction: Alkenes are the unsaturated hydrocarbons that react with substances that add to the double bond. Thus, they show addition reactions. Heat that is given off in the catalytic hydrogenation of an alkene is known as the heat of hydrogenation. The more substituted the double bond, the more stable is the alkene. A tri substituted double bond is the most stable and has the lowest heat of hydrogenation. A mono substituted double bond is the least stable and has the highest heat of hydrogenation.

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 .
