In a real-life scenario, a chemist discovers a compound with the formula $CH_{3} CH_{2} CH(CH_{3})CH_{2} CH_{2} OH$. What is the correct IUPAC name for this compound?
3-methylpentan-1-ol
Structural analysis of CH₃–CH₂–CH(CH₃)–CH₂–CH₂–OH:
- Number of carbon atoms in the longest chain containing –OH: 5 carbons → pentane backbone
- Functional group: –OH → an-1-ol (OH on C1)
- Substituent: –CH₃ on C3 → 3-methyl
IUPAC name: 3-methylpentan-1-ol
Numbering: start from the end closest to the –OH group (right end) → C1 has OH, C3 has methyl branch.
