The required energy to break a C=0 bond is 749kj/mol and the energy to break an H-O bond is 428kj/mol, so in order to form those bonds we have to add a - for each of those values. That means we will have to release 749x2 + 428x2 (2354kj/mol) of energy for every C we add to the chain. city garage porsche
