Please help me with the skeletal (line) structure of the following molecule:

Ethyl 2,6-diethyl-4,5,6-trihydroxy-3-oxooct-7-enoate

And this question has me stumped!...

An unknown compound W has the molecular formula C8H8 and so clearly has a large degree of unsaturation. However, when reacted with excess bromine the only product, compound X, has the molecular formula C8H8Br2. When more vigorous conditions are applied to compound X, including heat and a catalyst, two new compounds Y and Z are then formed each with the formula C8H7Br3.

Draw possible skeletal (line) structures that might represent the products W - Z.

                 -->                                           ---->
C8H8          Br2             C8H8Br2           Br2 / catalyst (Heat)               C8H7Br3

(W)                                (X)                                                         (Y and Z)




Thankyou, any help is appreciated.

One step at a time then. Can you recognize the functional group(s) in this molecule?

[Milsy]

No, I can't. Can you give me an idea how to recognise the functional group by the names in the molecule, I have been seraching for 'ethyl' 'diethyl' ect and I'm off track completely.

Do you know what "Ethyl" means?  What about "Hydroxy"?

Do you have a textbook for the course?  These are all things that are covered in naming organic compounds sections.  Hydroxy is going to be in the naming alcohols section, and ethyl should be in one of the first sections about naming, since it is a basic naming structure.
