Duchess · Answer 1

C-C bonds = 348 C=C bonds = 614 C (triple) bonds = 839

All in KJ/Mol

just do 839-614=225 and 614-348=266

After a pi bond is added on, these two numbers are the KJ/Mol it takes to separate the C-C bond,

To get the average: (225+266) / 2 = 245.5Kj/Mol

You might want to round your answer to 246KJ/Mol
