This is NOT homework, im just confused on how to name this organic compound. My chemistry teacher got quite of stumped, let alone i do not believe my fellow class mates in their idea of the name.

Example:

-----------------------------------------------------------------CH3
------------------------------------------------------------------|
OH-CH2-CH2-CH2(CH3)-CH3 + CH3COOH --> CH3-C-O-CH2-CH2-CH-CH3
--------------------------------------------------||
--------------------------------------------------O

(Sorry it's a bit hard to draw the compound on this; Im currently capped and can't be bothered uploading a picture to a website).

Anyways, back to the Question.

What is the name of the substance?

Ethanoic + 3 mthyl, butanol -> H2o + " 2 methyl, butanyl ethanoate"

I've always thought you are not able to get a functional group, on a functional group. Looking at this we notice the butyl functional group attached to the ester (ethanoate). Then there is also a methyl group of this?

If that is actually the name, can someone please guide me in the right direction? - What is the general rule with having a Functional Group/Functional Group.

(P.S I do understand you can obviously get two SEPERATE functional groups, i've just never encountered a functional group on another).

Thanks, recoil33

You are just trying too hard. Look at it from the other end.

Its just palin old 1-butyl acetate ( butyl acetate for short is ok.) plus a 3-methyl group.
so- 3-methylbutyl acetate

Example:

-----------------------------------------------------------------CH3
------------------------------------------------------------------|
OH-CH2-CH2-CH2(CH3)-CH3 + CH3COOH --> CH3-C-O-CH2-CH2-CH-CH3
--------------------------------------------------||
--------------------------------------------------O

It is even easier than that.... isoamyl acetate.

isoamyl alcohol (http://en.wikipedia.org/wiki/Amyl_alcohol) + acetic acid (http://en.wikipedia.org/wiki/Acetic_acid) <--H+--> isoamyl acetate (http://en.wikipedia.org/wiki/Isoamyl_acetate) + water

i think you need more practice so for practice you can go through these practice tests.


How would a biochemistry test help with organic chemistry. Stop link spamming.

:confused: Shome mishtake?

Ah, now I see what you mean, you put too few --- in

-----------------------------------------------------------------------CH3
-----------------------------------------------------------------------|
OH-CH2-CH2-CH2(CH3)-CH3 + CH3COOH --> CH3-C-O-CH2-CH2-CH-CH3
--------------------------------------------------||
