6. Select the right stability order for the following four Hexenes. Arrange the more stable alkene first. ex: I (if it is your most stable one) > II > III > IV. (A) I ＞ II ＞ III ＞ IV (B) II ＞ III ＞ I ＞ IV (C) III ＞ II ＞ I ＞ IV (D) IV ＞ I ＞ II ＞ III (E) III ＞ II ＞ IV ＞ I

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/molCH3-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 monosubstitutedcyclohexane (kJ/mol): (A) 9.2 (B) 22.8 (C) 32 (D) 16 (E) 11.4
