Is double bond more important than triple bond?

If a molecule contains both a double and a triple bond, the carbon chain is numbered so that the first multiple bond gets a lower number. If both bonds can be assigned the same number, the double bond takes precedence.

Do double bonds have higher priority in RS configuration?

Let’s try to determine the stereochemical configuration of the enantiomer on the left. Of the four bonds to the chiral center, the #4 priority is hydrogen. The nitrogen group is #1, the carbonyl side of the ring is #2, and the –CH2 side of the ring is #3.

Should a double bond have higher priority than a triple bond?

According to the priority table on Master Organic Chemistry, the opposite is true, and the triple bond should have priority. Also I saw this structure: According to the same priority table, shouldn’t a double bond have higher priority than a triple bond, and hence the numbering should start from the left?

How to name a compound with double bond and triple bond?

If both double bond and triple bond exist while naming a compound according to IUPAC system, to whom should i give importance first? Here is my understanding of the rules. Choose the longest continuous chain of carbon atoms, whether or not it contains multiple bonds. If there is a choice, choose the chain with more multiple bonds.

Which Bond has the higher priority – double bond or pent-1-en-4-yne?

In this case, the two possible numbering schemes lead to the same locant set of (1,4). However, according to the italicised portion of the quoted text, the double bond is considered to have the higher priority, and the name would correctly be pent-1-en-4-yne.

Why are double and triple bonds given low locants?

Numbers as low as possible are given to double and triple bonds as a set, even though this may at times give “-yne” a lower number than “-ene”. If a choice remains, preference for low locants is given to the double bonds.
