Question:

The heat of formation of (E)-1,3-pentadiene is 75.8 kJ mol^–1 (18.1 kcal mol^–1), and that of 1,4-pentadiene is 106.3 kJ mol^–1 (25.4 kcal mol^–1).

(a) Which alkene has the more stable arrangement of bonds?

(b) Calculate the heat liberated when one mole of 1,3-pentadiene is burned. The heat of combustion of carbon is 2393.5 kJ mol^–1 (294.05 kcal mol^–1), and that of H₂ is 2285.8 kJ mol^–1 (268.32 kcal mol^–1).
