Answer 1

59. Consider the following hypothetical reaction

3N(g) -> N6 (Aromatic)

if

B.E. N2 = 942 kJ mol-1

B.E. N-N = 170 kJ mol-1

B.E. N = N = 420 kJ mol-1

If resonance energy of product molecule is

-140 kJ mol-, determine the ∆Hf°; for the N6(cyclic)

(1) -140 kJ/mole

(2)916 kJ/mole

(3) 1056 kJ/mole ✔️✔️✔️

(4) 956 kJ/mole
