24i ma getting
968.89 units
RCM (50)
calculate the heat of the foll reaction:
CH3COCH3 + 2O2 → CH3COOH + CO2 + H2O
Bond energies :
C-H = 414.49
C-C = 347.92
C=O = 724.32
O=O = 494.04
O-H = 462.64
C-O = 967.13
Resonance energy :
-COOH = 117.23
CO2 = 138.16
Ans given is not matching with mine :(

This was simple
How did you guys made mistake here

Shouldnt it be 3*462.64 ???becoz there are 3 O-H bonds (1 in carboxylix acid and 2 in water)
1357oh I forgot to add that and got the correct answer.
maybe the answer given is wrong
1yup the answer given must be wrong.
I thought i was making some mistake that time...
