In line drawing only hetroatoms (atoms other than C and H) are shown. In 3-D structure, bonds lie above the plane is shown by solid bond and that lie below the plane by dashed bond. Bond which lie in the plane will be shown by normal bond.
In cis- structure, same groups lie on same side and in trans-, same groups lie in opposite side.

Conformations of the 1 - bromopropane molecule: Draw the line-bond structure of the 1-bromopropane molecule (C_3 H_7 Br). You will draw your Newman projection based on the rotation of the bond between the first and second carbon atoms (C1-C2). Highlight this carbon-carbon bond by drawing the bond as a bold line. Next, use your model kit to build a model of the molecule. Draw the Newman projection for each dihedral angle at 60 degree interval (from 0 degree to 360...

Draw the Newman projection in staggered
conformation for isoleucine by viewing the molecule along the
C?2??C?3 bond.
The perspective formula of isoleucine, an amino acid, is provided below. Draw the Newman projection in staggered conformation for isoleucine by viewing the molecule along the C-2-C-3 bond. Edit the Newman projection on the canvas. Replace the appropriate hydrogens with the appropriate -CH_3 or other groups. If you need to start over, Undo or choose a Newman projection from the Templates toolbar (bottom)....
