Which of the Following is True of the IUPAC System

Question

Which of the following is true of the IUPAC system of naming alkenes?
A) The alkene is always named based on the shortest carbon chain in a branched structure.
B) The position of the double bond is always given the highest possible number.
C) The position and identity of substituents determine the number associated with the position of the double bond.
D) None of these are correct.

Accepted Answer

The IUPAC system for naming alkenes involves selecting the longest carbon chain that contains the double bond, giving the double bond the lowest possible number, and naming substituents with their appropriate locants. Options A and B are incorrect because they describe practices opposite to the actual IUPAC conventions.
