Use Drago’s E and C parameters to calculate ΔH for the reactions of NH3 and BF3 and of NH3 and B(CH3)3. Compare your results with the reported experimental values of −71.1 and −64 kJ/mol for NH3—B(CH3)3 and −105 kJ/mol for NH3—BF3. use NH3 as the base, and put the four reactions in order of the magnitudes of their ΔH values.

Question
Use Drago’s E and C parameters to calculate ΔH for the reactions of NH3 and BF3 and of NH3 and B(CH3)3. Compare your results with the reported experimental values of −71.1 and −64 kJ/mol for NH3—B(CH3)3 and −105 kJ/mol for NH3—BF3.
use NH3 as the base, and put the four reactions in order of the magnitudes of their ΔH values.
Expert Solution
Step 1
The Drago's equation helps us to calculate the enthalpy and thereby the bond strength of acid- base or donor-acceptor interactions. It use two parameters which are empirically obtained i.e. E which describes electrostatic interaction and C for covalent interaction.
