13. (a) The conformations of some highly substituted cyclohexanes were studied (Dalton Trans 2013, 42, 13404). The two chair conformations for compound J differ by 18 kcal/mol, draw the more stable chair conformation of compound J. Include all 6 substituents and the hydrogen atoin groups associated with each vertex. Take care to create a clear drawing (11o11-boricding electrons do not need to be shown). N(CH3)2...
