Question

wht is hydrogenation enthalpy?​

Answer 1

Explanation:

Enthalpy of hydrogenation is defined as the change in enthalpy, which occurs when one mole of an unsaturated compound reacts with an excess of hydrogen to become fully saturated at atmospheric pressure and room temperature, the reactants and products being in their natural states under these conditions.

Answer 2

Answer:

Heat of hydrogenation (symbol: ΔHhydro, ΔHº) of an alkene is the standard enthalpy of catalytic hydrogenation of an alkene. Catalytic hydrogenation of an alkene is always exothermic. ... Heat of hydrogenation of alkenes is a measure of the stability of carbon-carbon double bonds
