5. a) Using Drago and Waylands E and C equation, calculate the enthalpy of adduct formation for the reaction of pyridine with BF3 and pyridine with B(CH3)3. Compare your results with the reported experimental values of 25.10 kcal/mol for pyridineBF3 and 16.99 kcal/mol for pyridineB(CH3)3. Note: See the tables on the last page for E and C values.

b) Compare your calculated delta H values for pyridineBF3 and pyridineB(CH3)3. Explain the differences in terms of the structures of BF3 and B(CH3)3
