Which formula corresponds to 1-butanol?

Which formula corresponds to 1-butanol?

• A. CH₃CH₃
• B. CH₂OHCH₂CH₂CH₃
• C. CH₃CH₂CH₃
• D. CH₃CH₂CH₂CH₃

Answer: (B)

The correct choice for the formula corresponding to 1-butanol is not B. The proper structural formula for 1-butanol is actually represented by the choice that depicts a four-carbon straight-chain alcohol with an -OH functional group at the first carbon. 1-butanol, a primary alcohol, has the molecular formula C₄H₁₀O, which can be visualized as follows: CH₃-CH₂-CH₂-CH₂OH. This indicates a four-carbon chain (butane) with an -OH group attached to the first carbon. Option B incorrectly represents the structure. While it contains the -OH group, the layout and connectivity of the carbon atoms do not accurately reflect 1-butanol's structure. The choice that correctly represents 1-butanol showcases the straight-chain form and the position of the hydroxyl group at the terminal carbon. This structure indicates that the alcohol is located at the terminal end of the butane chain, classifying it as a primary alcohol. Therefore, the correct answer aligns with the primary alcohol format, distinctly showcasing four carbon atoms with the -OH group attached at the first position, making it clear that it is 1-butanol.
