Repeat Prob. 16.14(b) using B3LYP/6-31G* calculations.
In Repeat Prob. 16.14(b)
(b) Do HF/6-31G* energy and vibrational frequency calculations on the molecules in the CH3 CHO bond-separation reaction. Scale the vibrational frequencies (Section 15.12) to find the zero-point energies. Find the ∆H0 value predicted by the HF/6-31G* method for the gas-phase CH3CHO bond-separation reaction. Compare with the experimental value of 11.5kcal/mol.
