Name________KEY__________________
1. (2 pts each) Give the IUPAC name for each of the following molecules.
_2,2,5-trimethylhexane________ ____4,6-dimethylnonane_____ _____ethylcyclopentane____
2. (2 pts) Draw the most stable isomer of 1,2-dimethylcyclohexane in a chair conformation. Label both methyl substituents as axial or equatorial. You may do scratch work in the space below, but draw your answer in the box. Only answers in the box will be graded - you will get no credit for an answer not in the box, even if it is correct!
3. (2 pts) Looking along the bond between carbons 2 and 3 of butane, there are two different staggered conformations and two different eclipsed conformations. Draw a Newman projection of the most stable conformation out of the four. As in #2, only answers in the box will be graded - you will get no credit for an answer not in the box, even if it is correct!
