AIIMS 2019 Chemistry IUPAC Nomenclature MCQ Question
Number starts from terminal carbon which has nearest branching.
Correct Answer
Detailed Explanation
In organic chemistry, when numbering the carbon chain of a branched alkane, the numbering begins from the terminal carbon that is closest to a substituent or branching point. This ensures that the substituents receive the lowest possible numbers, which is a fundamental rule in IUPAC nomenclature. Option C correctly identifies this principle, while options A and B do not provide relevant information or context, making them incorrect. Understanding this concept is crucial for accurately naming organic compounds and recognizing their structure.
