Answer
The parent will be called "hex".
Work Step by Step
This parent will be called "hex".
1. Is there a functional group?
If there are any functional groups, mark the part that has it. (Until a bifurcation.)
2. Is there a double bond?
If there are any double bond, mark the part that has it. (Until a bifurcation, and unless this violates the first step.)
3. Is there a triple bond?
If there are any triple bonds, mark the part that has them. (Until a bifurcation, and unless this violates the first or the second steps.)
4. Find the longest chain of carbons.
** Hint: Look for bifurcations, and choose the two who have the largest number of carbons. (Not violating the steps 1, 2 or 3.)
Do it for all bifurcations.
5. Count the number of carbons on the largest chain, and use the table on page 88 to know what parent name will be used.
