Bond energies can be used to estimate the energy of a reaction. Why is this only an estimate?
A) It's difficult to isolate an individual bond.
B) It's difficult to measure such a small amount of energy.
The same bond in a different molecule has a different energy. For example,
C
O-H in water versus ethanol has different energies.
D) The bonds in all molecules are the same, but not all molecules have bonds
that are easily measured.
