Chemistry 100 G Homework 1

14. Table 5.3 on page 84 of Joesten & Hogg shows the bond energies of carbon-carbonbonds. The bond energy is the amount of energy needed to break the bond. The tableshows that a C-C single bond has a bond energy of 83 kcal/mole. This means it takes83 kcal of energy to break a certain number of C-C single bonds. The table shouldsay the bond energy of a C=C double bond is 146 kcal/mole. This means it takes 146kcal/mole to break both bonds in the double bond.a. How much energy does it take to break only the second bond in a C=C doublebond so that it ends with a C-C single bond? (The bond energy of the doublebond is the sum of the bond energy of the single bond and the bond energy of thesecond bond in the double bond.)b. How does the energy needed to break only the second bond compare to the energy needed tobreak a C-C single bond?15.
