Consider the following thermochemical equation: C2H4+H2→C2H6; △H1= – InterviewSolution

1.	Consider the following thermochemical equation: C2H4+H2→C2H6; △H1=−32.7 kcal 1,3−butadiene+2H2→C4H10; △H2=−40.2 kcal Therefore the magnitude of resonance energy of 1,3-butadiene is: kcal
Answer» Consider the following thermochemical equation: $C_{2} H_{4} + H_{2} \to C_{2} H_{6}; △ H_{1} = - 32.7 k c a l$ $1, 3 - b u t a d i e n e + 2 H_{2} \to C_{4} H_{10}; △ H_{2} = - 40.2 k c a l$ Therefore the magnitude of resonance energy of 1,3-butadiene is: $k c a l$
