Quick question about nomenclature

[somebody]

Ok, when naming organic compounds, For alkanes, i know that you alphabetize constituents name, but you do not alphabetize the di, tri, tetra...

 

 

how about the iso , sec and tert? do you alphabetize that because my professor said yes but book does not!

 

 

thanks

I think it may be a matter of preference, but technically, yes you should alphabetize all other parts of organic compounds.

That's just one of those real specific nomenclature rules. :esmoking:

You do not. They, in essentiality, are only like special names for the usual ones like di, tri etc.

Perhaps I misunderstood the question?

Is he talking about alphabetizing them in relation to eachother in the compound, or the other constituents?:eek:

ook, that kinda makes sence since isobutyl is like 2-methylbutyl.

 

alright that mean, i need to have talk with my professor!

 

and my question was that if you have isopropyl and butyl what comes first in naming compound is it the isopropyl or the butyl

[ronthepon]

Oh, sorry about the misunderstanding.

 

butyl comes first, and then comes isopropyl

The naming convention helps one draw the structure using words. For example, 2-methyl butyl, tells us to start with butyl as the backbone and at the 2 position one adds a methyl group.
