4. trans-1-tert-Butyl-4-isopropylcyclohexane has two conformers. Using the following data to calculate the strain in this two conformers, by how much kJ/mol that one is favored than the other?If,

H-C-C-H eclipsed interaction strain: 4 kJ/mol;
CH3-C-C-H eclipsed interaction strain: 6 kJ/mol
CH3-C-C-CH3 eclipsed interaction strain: 11 kJ/mol;
CH3-C-C-CH3 gauche interaction strain: 3.8 kJ/mol
     Each one      strain (S) of 1, 3-X-H diaxial interaction in monosubstituted
cyclohexane (kJ/mol):

 
(A) 9.2
(B) 22.8
(C) 32
(D) 16
(E) 11.4
