Q. Which of the following is the correct IUPAC name for CH3-CH2-CH(CH3)-OH?
A.
2-Methylpropan-1-ol
B.
3-Methylbutan-1-ol
C.
2-Methylbutan-1-ol
D.
3-Methylpropan-1-ol
Solution
The longest chain has four carbons, and the hydroxyl group is on the first carbon, with a methyl group on the second carbon, making it 2-Methylbutan-1-ol.
