Convert the following Newman projections to skeletal structures and name them.
a.
b.

Convert each Newman projection to the equivalent line–angle formula, and assign the IUPAC name.

(a)

(b)

Draw a Newman projection, similar to Figure 3-25 down the C1—C6 bond in the ­equatorial conformation of methylcyclohexane. Show that the equatorial methyl group is also anti to C5. (Using your models will help.)

<IMAGE>

Draw Newman projections of the following molecules viewed from the direction of the blue arrows.

(b)

Draw Newman projections of the following molecules viewed from the direction of the blue arrows.

(a)

Draw all the staggered and eclipsed conformers that result from rotation about the C-2-C-3 bond of pentane.

Using Newman projections, draw the most stable conformer for each of the following:

b. 3-methylhexane, viewed along the C-3----C-4 bond

Using Newman projections, draw the most stable conformer for each of the following:

a. 3-methylpentane, viewed along the C-2---C-3 bond

Draw a potential-energy diagram for rotation about the C-2---C-3 bond of pentane through 360°, starting with the least stable conformer.
