Sighting down the C1-C2 bond axis of 1-chloropropane, draw the Newman projection of, a) the anti staggered conformer. b) the gauche staggered conformer. the two eclipsed conformers. c)

Draw the most stable conformer of the following molecule. (A solid wedge points out of the plane of the paper toward the viewer. A hatched wedgepoints back from the plane of the paper away from the viewer.)

a) Draw all Newman projections of your molecule's conformations in which the CH3 group and the H of the CHY2 group are positioned 'ANTI' to each other. Be sure to put in the correct X and Y atoms, bonded to the correct C atoms, for your molecule. X = FY=I Conformations = 60 deg and - 180 deg 60 deg dihedral angle = - 179.987 deg 180 deg · - dihedral angle = 179.814 deg

Monosubstituted cyclohexanes occur in two equilibrium conformations. In one conformation, the substituent is in an axial position. In the other conformation, the substituent is in the equatorial position. Complete the drawing of each chair conformation below and circle the more stable conformation.

Draw the conformations of pentane using a Newman projection of the view along the C2-C3 bond. Identify the least stable conformation.

Consider the following chair conformation of bromocyclohexane: H H H Br H H H (a) Identify whether the bromine atom occupies an axial position or an equatorial position in the conformation above. (b) Draw a bond-line drawing (skeletal structure) of this chair conformation (without Newman projections). (c) Draw a bond-line drawing of the other chair conformation (after a ring flip).
