Although you may
make many different
products, in principle
all of them have the
same
molecular
weight, so you can still calculate a theoretical yield.

3) You are using a mixture of cis and trans isomers rather than a pure cis or trans methylcyclohexanol
precursor. Considering the mechanism, explain whether you would expect a significant different if a pure
mixture of one isomer was used.
4) Explain which product should predominate during the dehydration of 2-methylcyclohexanol, and why?
5) What are the boiling points of all of the possible methyl cyclohexene products?
