Chapter 18, Problem 107RQ

The standard heat of formation of ethanol vapor, ${\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\text{OH,}\left(g\right)\text{ is -235}{\text{.3 kJ mol}}^{\text{-1}}$. Use the data in Table 18.3 and the average bond energies for C—C, C—H, and O—H bonds to estimate the C—O bond energy in this molecule. The structure of the molecule is
