Give the IUPAC name for the following compound

1-cyclopentylhexane

4

Draw an appropriate structure given the IUPAC name of the following compound:

5-sec-butyl-3-ethyl-2,7-dimethyldecane

5

Draw an appropriate structure given the IUPAC name of the following compound:

4-ethyl-3,6-dimethyloctane

Convert the following structure to a Newman Projection. Rotate projection 60 degrees and identify which conformation is more stable.

card image

**The rotated conformation is neither the most or least stable. The least stable would have the methyl groups eclipsing each other.

7
card image

Convert the following structure to a Newman Projection (The eye is on the lefthand side). Rotate projection 60 degrees and identify which conformation is higher in energy.

Classify the following reaction as oxidation, reduction, or neither.

Neither

9

Classify the following reaction as oxidation, reduction, or neither.

Oxidation

Draw another conformer of the structure provided of cis-cyclohexane-1,3-diol. Identify which is most stable.

card image

The conformer following the ring flip is more stable because the substituents (large groups) are avoiding 1,3-trans-diaxial interactions.

11

Draw an appropriate conformer for cis-1-ethyl-3-isopropylcyclohexane. Perform a ring flip, and then determine which is the least stable conformation.
