Question

what is heat of hydrogenation

Answer 1

Heat of hydrogenation (symbol: ΔHhydro, ΔHº) of an alkene is the standard enthalpy of catalytic hydrogenation of an alkene. ... Thus, heat of hydrogenation of 1-butene is -30.3 kcalmol-1. Heat of hydrogenation of alkenes is a measure of the stability of carbon-carbon double bonds.

Answer 2

Explanation:

Heat of hydrogenation of alkenes is a measure of the stability of carbon-carbon double bonds. All else being the same, the smaller the numerical value of heat of hydrogenation of an alkene, the more stable the double bond therein.
