(a)
To determine: The rank of each compound in order of increasing heat of hydrogenation.
Interpretation: The rank of each compound in order of increasing heat of hydrogenation is to be shown.
Concept introduction: Heat of hydrogenation aids in find out the stability of double bonded compounds. The addition of hydrogen atom in an unsaturated compound known as hydrogenation and the amount of energy released during the process of hydrogenation known as heat of hydrogenation. Heat of hydrogenation is always shown by negative sign; if the value of heat of hydrogenation is small then double bonded compounds possess more stability and vice-versa.
