    The heat of hydrogenation is less than expected because benzene is stabilized by resonance

    eduncle-logo-app

    sir as double bond increases heat of hydrogenation increases but for benzene exception due to delocalisation right

    eduncle-logo-app

    yes...it is less than expected

    eduncle-logo-app

    due to aromatic nature of benzene it is stable

    so overall order becomes 2>3>1
