Question

Heat of formation of benzene assuming no resonance givrn that

Answer 1

Answer:

If the benzene has no resonance, then there will be carbon and hydrogen for the reactant and the benzene alone for the product. The reaction is 6C+3H2 -> C6H6. So, the heat of the reactant will be 6*170.9 for carbon and for hydrogen will be 104.2*3 which on solving we will get 1338 kcal
