10. If a H exhibits a triplet at δ 1.105, 1.085, and 1.065 ppm, data collected by a 300 MHz NMR. Where will this triplet peaks show up (δ:ppm) if this same sample was measured in a 600 MHz NMR? (A) 1.105, 1.085, 1.065 (B) 1.105, 1.095, 1.085 (C) 1.115, 1.085, 1.055 (D) 1.095, 1.085, 1.075 (E) 1.085, 1.075, 1.065

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
