QUIZ FOR CHAPTER 4 Question #3: What is the value of the 1,3-diaxial strain between the methyl (error, should have been ethyl) and the hydroxy (OH) substituent groups in the following molecule? It is known that the 1,3-diequatorial conformation is 19 kJ/mole more stable than the 1,3-diaxial conformation. The 1,3-diaxial strain between a hydroxy (OH) and an ethyl group would be: 19kJ/mole –[(4.0 kJ/mol) + 2.1 kJ/mole)]
