Concept introduction:
In a cyclohexane ring, the steric interactions that takes place between an axial substituent located on the carbon atom 1 and the hydrogen atoms located on carbon 3 and 5 is known as 1, 3 diaxial interaction. In the cyclohexane derivatives, each 1, 3-diaxial interaction between the methyl and hydrogen increases the enthalpy of the ring by
