What functional group is this?

[kyzoo]

True, I've learned a lot from my Chem and Physics teachers that wasn't in the textbook

lol.....jacaranda has heaps of mistakes...
looks like i have to read over heinemann as well

[crayolé]

I use Heinemann and I never seen that test before 0.o I would guess that Mao most likely obtained this info from an external company's Chem practice exam solutions.

It's pretty much applying your knowledge of organic pathways anyway.

Alkanol -----Cr₂O₇ Catalyst------->> Carboxylic acid
and then esterification
All the in between steps arent really needed are they?

have a look~~!

I don't think you should leave the aldehyde step out.

[cindyy]

pretty sure our teacher has NEVER mentioned this aldehyde + ketone stuff, thank god for vce notes

Yeah it will probably make you look a more competent student thus more deserving of marks but I was at a tsfx lecture and the lady said that the intermediate step with aldehydes and ketones werent needed in the exam?

[Mao]

As far as I know, you won't need to know any intermediates. However, you should be aware of what aldehydes and ketones are, how they are derived, what chemical pathways they can undergo, and what chemical pathways lead to them.

I don't really understand how the textbooks, with so much irrelevant information (such as bus companies and their efforts to be environmentally friendly), can miss these more relevant aspects such as aldehydes.

Aha true tbh theres so much bs in the green chemistry
