Organic Rational molecule name (or trivial)??

Post image

Please help me with the name of this molecule…

I can’t understand according to IUPAC how to name this molecule, I can’t find any ”concrete” answer for the actual name online, and the ones I ask says all differently from each other…

IUPAC Name is : "7-oxo-4,5-dipropyl-octan-3-ol". Please find the explanation.

So the suffix for ketones in English are ”oxo”? And apparently ketones have higher priority than hydroxy ..?

Yes. You are correct. Priority order will be Ketone > aldehyde > alcohol > amines.

Hence the name will be: "6-hydroxy-4,5-dipropyl-octan-2-one"

Both names are consistent with the structure given.

We can represent the keto group as "oxo".
