the only thing VCAA asks you to name with carbonyl groups are esters

I'm pretty sure

Carbonyl group = ketone group (sometimes)

But we don't even need to know about ketones and aldehydes.

VCAA 08 begs to differ.


.......But that question on 08 could be done with simple logic.

We didn't have to name it though, they just wanted the structure which, as you said, is easily determined using the given NMR data and some logic..

For that question since I knew what a ketone was i immediately just went bang ketone thank you 2 marks.

I guess an understanding would be good if you are looking for mega marks.... but it aint in the study design. You are correct.
