Double/triple bonds and Functional Groups
When numbering Carbons in the main chain, do double/triple bonds take priority over functional groups or do functional groups take priority over double/triple bonds?

Re: Double/triple bonds and Functional Groups
Functional groups come before
ex) 2-chlorobutane is correct
2-butalchlorine or anything else is incorrect
ex) phenylalanine
ex) 2-methylbutane
ex) 2-chlorobutane is correct
2-butalchlorine or anything else is incorrect
ex) phenylalanine
ex) 2-methylbutane

Re: Double/triple bonds and Functional Groups
Sorry I think you misunderstood my question. What I was trying to ask is would you give functional groups the lowest number when numbering carbons in the main chain or double/triple bonded carbons the lowest number?

Re: Double/triple bonds and Functional Groups
Double and triple bonds are considered functional groups. However they are relatively low in the order of priority so you tend to number other function groups first. See the attached doc for some examples.
