Web1) You have to put energy into a bond (any bond) to break it. Bond breaking is endothermic. Let's break all the bonds of the reactants: one C≡C ⇒ +839 kJ two C−H ⇒ 413 x 2 = +826 kJ two H−H ⇒ 432 x 2 = +864 kJ The sum is +2529 kJ Note there are two C−H bonds in one molecule of C 2 H 2 and there is one H−H bond in each of two H 2 molecules. WebMolecular oxygen, O 2, is photolyzed by light of 241 nm and has a bond energy of 498 kJ/mol. Hydrogen peroxide, HOOH, has a very weak O-O bond and is photolyzed by light of 845 nm. Its bond energy is only about 142 kJ/mol. Why do we see such large difference in the strength of oxygen-oxygen bonds in these molecules.
