Question

10. Heat of formation of benzene, assuming noresonance. Given thatBE (C-C) = 83 kcalBE (C=C) = 140 kcalBE (C-H) = 99 kcalCo Heat of atomisation of C = 170.9 kcalTu Mo Heat of atomisation of H = 104.2 kcalwill beEB(1) 39 kcal(2) 75 kcal​

Answer 1

first find total heat of formation of product

then total heat of formation of reactant

heat of formation = heat of reactant -heat of product
