    eduncle-logo-app

    individual pair

    eduncle-logo-app

    for 2nd one dienes has more HOH than alkynes greater the number of double bonds, greater the amount of heat evolved in hydrogenation.

    eduncle-logo-app

    for 1st .... 2nd has more HOH

    eduncle-logo-app

    2nd one is antiaromatic less stable...and the smaller the numerical value of heat of hydrogenation of an alkene, the more stable the double bond.
