Sabatier Senderen's reaction is an example of:
Correct answer: B. Exothermic reaction
- A. Non thermic reaction
- B. Exothermic reaction
- C. Endothermic reaction
- D. None
Explanation
During Sabatier-Sendern reaction, hydrogenation of alkene occurs, that breaks the doubke bond to produce single bond. The energy released in the formation of two sigma bonds is 174 kcal so the net released energy is 30 kcal/mole (i.e. in one step, in the formation of alkene from alkyne). This is called heat of hydrogenation (i.e. exothermic reaction).

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
