question 8 (1 point)
what is the iupac name for the following molecule?
2,2 - dimethyl - 6 - ethylheptane
6,6 - dimethyl - 2 - ethylheptane
2,2,6 - trimethyloctane
2,2,2 - trimethyl - 6 - ethylhexane

Explanation:

1. First, find the longest carbon - chain. The longest chain has 8 carbon atoms, so the parent name is octane.
2. Then, number the carbon - chain to give the substituents the lowest possible numbers. There are two methyl groups on the second carbon and one methyl group on the sixth carbon.
3. According to IUPAC naming rules for alkanes, the name is 2,2,6 - trimethyloctane.

Answer:

C. 2,2,6 - trimethyloctane
