Question 1 Consider the following molecule and answer the questions that follow. CH-CH:CH-CH-CH.CH a) While sighting along the C3-C4 bond, draw the MOST STABLE conformation of this molecule using a Newman projection (also known as a Fischer projection). (2) b) While sighting along the C3-C4 bond, draw the LEAST STABLE conformation of this molecule using a Newman projection (also known as a Fischer projection). (2) c) What factors increase the energy of the least stable conformation in Question 1b above? (2) d) Sketch a simple energy profile (potential energy versus dihedral angle) to show how the energy of the molecule changes during a full 360° rotation about the single bond C3-C4 beginning with the energy of your least stable conformation (Question 1b).
