Consider 2-methylbutane (isopentane). Looking along the C2-C3 bond: a) Draw a Newmann projection of the most stable conformation. b) Draw a Newmann projection of the least stable conformation. c) Indicate the gauche form. d) State the eclipsed Newmann projection. An eclipsed CH3-CH3 interaction has an energy value of 11 kJ / mol and a gauche CH3-CH3 interaction has an energy value of 3.8 kJ / mol, the data are given if you need them.
