draw (cis)-1-ethyl-3-methylcyclohexane and then show the conformation resulting from ring flip. Circle the most stable conformation. im really behind and not understanding. could you please not only draw but explain why which is more stable and why they are draw the way they are drawn. I dont even know what a ring flip is. i need a step by step process please
