The experimental melting point we obtained at the end for the cis and trans mixture of 4-t-butylcyclohexanols was 68-70 degrees Celsius. How do you interpret the experimental MP for this lab when the theoretical melting point is 82-83 for trans and 81-82 degrees for cis? Does it melt as expected for a mixture of cis and trans isomers?
