Question

what is the iupac name for the compound shown?
iupac name:

Explanation:

1. First, identify the longest continuous carbon chain (parent chain): this is 5 carbons long, so the base name is "pentane".
2. Number the parent chain from the end closest to substituents: numbering from the right gives substituents at positions 2 and 2.
3. Identify substituents: there are two methyl groups ($-\text{CH}_3$) on carbon 2. Use the prefix "di-" for two identical substituents.
4. Combine the parts: list substituents with their position, then the parent chain name.

Answer:

2,2-dimethylpentane
