Problem

Acetic acid is responsible for the sour taste of vinegar. It can be manufactured using the following reaction:

Use tabulated values of bond energies from the following table to estimate ΔE for this reaction.

Solution
  • Analyze the bonds present in each reactant and products and get the difference of their bond energies

ΔE  = Σ Average bond energy of reactants -  Σ Average bond energy of products

  • Remember that reactants are breaking bonds while products are forming bonds 
  • For the reactants, CH3OH has 3 C-H bonds, 1 C-O and 1 O-H then 1 C≡O
  • For the product, acetic acid, 3 C-H, 1 C-C, 1 C=O, 1 C-O and 1 O-H
