Text Solution

AI Generated Solution

To determine which of the given compounds has the highest heat of hydrogenation, we need to analyze the stability of the alkenes mentioned in the options: butane, cis-butene, trans-butene, and isobutane. ### Step-by-Step Solution: 1. **Understanding Heat of Hydrogenation**: - Heat of hydrogenation refers to the standard enthalpy change when an alkene is hydrogenated to an alkane. It is an exothermic process, meaning energy is released. - The heat of hydrogenation is inversely proportional to the stability of the alkene; a less stable alkene will have a higher (more negative) heat of hydrogenation. ...
