Which of the following is the correct IUPAC name for CH3-CH2-CH(OH)-CH3? (2020)

Which of the following is the correct IUPAC name for CH3-CH2-CH(OH)-CH3? (2020)

Step 1: Identify the longest carbon chain in the compound. In CH3-CH2-CH(OH)-CH3, the longest chain has 4 carbon atoms.
Step 2: Number the carbon atoms in the chain from one end to the other. Start from the end closest to the hydroxyl (OH) group.
Step 3: Assign numbers to the carbon atoms. The first carbon is CH3, the second carbon is CH(OH), the third carbon is CH2, and the fourth carbon is CH3.
Step 4: Identify the position of the hydroxyl (OH) group. It is on the second carbon.
Step 5: Use the IUPAC naming rules. Since there are 4 carbons, the base name is 'butane'. Because there is an OH group, it becomes 'butanol'.
Step 6: Combine the position of the OH group with the base name. Since the OH is on the second carbon, the name is '2-butanol'.
