Question & Answer
Choose the Best Answer
It gives the lowest possible numbers to the substituents.
It is a common practice to start numbering from the most stable carbon.
It follows alphabetical order of substituents.
The angle strain is lower when starting from carbon 1.
Understanding the Answer
Let's break down why this is correct
Choosing carbon 1 as the starting point gives the substituents the smallest possible numbers. Other options are incorrect because The rule does not use the most stable carbon as a reference point; Alphabetical order matters for listing substituent names, not for choosing where to start counting.

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.
