Question

Draw both the chair and boat conformation of 1,4-dimethylcyclohexane with the methyl groups as cis and trans for both conformations. Label your molecules for cis and trans. Tell which is the highest in energy.

Answer 1

Boat conformation cis 1,4-dimethyl cyclohexane has the highest energy.

Step-by-step explanation:

From the conformations, the boat conformation cis 1,4-dimethyl cyclohexane is least stable due to the fact that two methyl groups are located in opposite direction to each other, this leads to the production of a higher strain. Similarly, Chair conformations appear more stable than boat conformation. Hence, energy is inversely proportional to stability. As a result of the aforementioned, boat conformation cis 1,4-dimethyl cyclohexane has the highest energy.
