Answer
The IUPAC name for that compound is: "2,3-dimethylpentane"
A line-angle formula of that compound is in the following image:
Work Step by Step
1. Draw the bond between the 2 main carbons.
- Both main carbon atoms are highlighted.
2. Add the groups connected to the carbon on the line-angle drawing. (Except the Hydrogens).
3. Convert the groups formulas to the line-angle drawing style. Don't forget: the group chain starts at the marked carbon, so a methyl group ($CH_3$) is a line attached to that carbon, and a ethyl is two lines.
