The concept of resonance explains various properties of compounds. The molecules with conjugated system of π bonds, are stabilized by resonace and  have low heat of hydrogenation. Hyperconjugative stabilization also decreases heat of hydrogenation. In aromatic rings a functional group with a lone pair of electron exerts + m effect. Some functional groups like –NO, –NC, –CH=CH2 can function both as electron releasing (+m, +R) or electron withdrawing (– m, – R) groups. More extended conjugation provides more stabilization.
Q. The correct heat of hydrogenation order is 
(p) 1, 3-Pentadiene                              (q) 1, 3-Butadiene
(r) 2, 3-Dimethyl-1, 3-butadiene             (s) Propadiene
  • a)
    p > q > r > s    
  • b)
    s > q > p > r    
  • c)
    q > s > p > r    
  • d)
    s > p > q > r
