Which compound is the IUPAC name 2-methylbutan-2-ol assigned to?
ACH₃CH(OH)CH₂CH₃ (butan-2-ol)
B(CH₃)₃C-OH (3° alcohol; t-butanol)
CHOCH₂CH₂CH₂CH₃ (butan-1-ol)
D(CH₃)₂C(OH)CH₂CH₃ — tertiary alcohol; OH at C2 (which has 2 CH₃ + 1 CH₂CH₃)
Answer & Solution
Correct answer: D. (CH₃)₂C(OH)CH₂CH₃ — tertiary alcohol; OH at C2 (which has 2 CH₃ + 1 CH₂CH₃)
**2-Methylbutan-2-ol**: 4-carbon main chain (butan-), -OH at C2 (-2-ol), methyl branch at C2 (2-methyl). Structure: **(CH₃)₂C(OH)CH₂CH₃** — a tertiary alcohol. (CH₃)₃COH is **2-methylpropan-2-ol** (t-butanol).
