The reason why heat of hydrogenation for cis isomer is larger than trans isomer has to be indicated. Concept Introduction: Hydrogenation: It is the reaction between compounds with unsaturated bonds and within H 2 presence of catalyst that results to add hydrogens across the double bonds present in the compound. Syn addition: When two substituents are added over double or triple bond on same side of the compound simultaneously is called syn addition. Syn elimination: When two substituents bonded in same side of a compound gets cleaved from the substance simultaneously then the elimination is called syn elimination. cis isomer: The compound with two functional groups are present on same side of the carbon chain. Trans isomer: The compound with two functional groups are present on opposite side of the carbon chain.
