NEET Chemistry IUPAC Nomenclature Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 11
Assertion (A): In IUPAC nomenclature, the principal functional group is always given the lowest possible number in the carbon chain.
Reason (R): The longest carbon chain is the parent chain in a compound with multiple functional groups.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option B
Detailed Explanation
The IUPAC rules prioritize the numbering of the principal functional group with the lowest possible number, but the explanation about the longest carbon chain being the parent chain does not directly explain this priority.
