Question

Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE.

Long and detailed explanations are not needed. Keep it short, brief, and direct because I only need the answers as soon as possible.

Calculate the total strain energy in each of the two chair conformations of cis-1-tert-butyl-4-chlorocyclohexane. By how much energy is the more stable conformation favored (this is the difference in energy between the two conformations)?

NOTE: The strain energy for one H,Cl interaction is 1.0 kJ/mol while for H,-C(CH3)3 (t-butyl) is 11.4 kJ/mol.
