The method using bond enthalpies is the least accurate since for many different molecules – that are not diatomic– the bond enthalpies are averages.

Method 2 that Lavelle went over in class, aka the one that uses bond enthalpies to calculate the enthalpy.

I believe the second method that Dr. Lavelle covered in lecture that uses bond enthalpies to calculate the total enthalpy is the least accurate method.
