A team of chemists is developing a new drug that involves a cyclohexane ring structure with multiple substituents. They need to name their compound correctly to ensure clarity in communication and research. If one substituent is a methyl group and another is a hydroxyl group, while the hydroxyl group is positioned at carbon 1 and the methyl group at carbon 3, what is the correct IUPAC name for the compound?

A

3-methylcyclohexanol

B

1-hydroxy-3-methylcyclohexane

C

1-methyl-3-cyclohexanol

D

1-hydroxycyclohexane

Understanding the Answer

Let's break down why this is correct

The hydroxyl group is a functional group and gets the lowest number. Other options are incorrect because It puts the methyl group name before the hydroxyl; It reverses the order of substituent names.

Definition

Naming cycloalkanes involves adding the prefix 'cyclo-' before the root name, numbering carbons to give substituents the lowest possible numbers, and alphabetically ordering substituents. The naming also includes using prefixes like cis- and trans- based on the orientation of substituents on the ring, with cyclopentanes and cyclohexanes being the most common due to their stability and low ring strain.
