Answer
2-Methyl-3-butanol

The correct answer is 2-Methyl-3-butanol — Combine the pieces to form the name: 2-methyl-3-butanol.

Step-by-step solution

  1. Identify the longest continuous carbon chain containing the OH group: 4 carbons.
  2. Number the chain to give the OH the lowest possible number, resulting in OH on carbon 3.
  3. Identify the substituent: a methyl group on carbon 2.
  4. Combine the pieces to form the name: 2-methyl-3-butanol.
Common mistake: Choosing a parent chain that gives the OH a higher number instead of the lowest
