Which statement(s) about enthalpy is true about bond enthalpy?

a. The bond energy for a triple bond between A and B is three times of a single bond between A

and B.

b.  for the breaking of a bond is always a negative number.

c. Energy is required to make a bond.

d. Bond enthalpy is defined only for bonds broken or formed in the gaseous state.

e. The presence of pi bonds does not influence the geometry of a molecule. However, the presence of pi bonds affects the value of the bond enthalpy between two atoms.

Average bond enthalpies are generally defined for gas-phase molecules. Many substances are liquids in their standard state. (Section 5.7) By using appropriate thermochemical data from Appendix C, calculate average bond enthalpies in the liquid state for the following bonds, and compare these values to the gas-phase values given in Table 8.4: (a) Br – Br, from Br2(l); (b) C – Cl, from CCl4(l); (c) O – O, from H2O2(l) (assume that the O – H bond enthalpy is the same as that in the gas phase). (d) Does the process of breaking bonds in the liquid as compared to the gas phase cost more energy? Explain the difference in the ∆H values between the two phases.
