Question & Answer
Choose the Best Answer
1-methylcyclohexane
Cyclohexylmethane
Hexamethylcyclohexane
Cyclohexane-1-methyl
Understanding the Answer
Let's break down why this is correct
The name starts with the prefix for the substituent, here "1-methyl", followed by the ring name "cyclohexane". Other options are incorrect because "Cyclohexylmethane" sounds like a chain of methane units linked to a cyclohexyl group, which is a different structure; "Hexamethylcyclohexane" suggests six methyl groups attached to the ring, not a single one.

Deep Dive: Cycloalkanes Naming
Master the fundamentals
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.
