Vedclass · Answer

(B) The heat of hydrogenation is inversely proportional to the stability of the alkene. More substituted or more stable alkenes release less heat upon hydrogenation. Among the given options,$Trans-2-$butene is the most stable isomer due to minimal steric hindrance and greater symmetry compared to $Cis-2-$butene and $1-$butene. Therefore,$Trans-2-$butene releases the lowest quantity of heat upon catalytic hydrogenation.

One mole of each of the following alkenes is catalytically hydrogenated. The quantity of heat evolved will be the lowest in the case of
