Last minute questions?

1) I've always had some sort of a problem splitting up structures for identifying fragments in IR spec...
HCOOCH(CH3)2

Can't that split into OCH(CH3)2 for a peak at a m/e ratio of 59?
It adds up to 59 hah but yeah i know it looks weird...and someone can tell me the best to identify fragments please

2) 3-bromo-2-methyl-pentane
or 2-methyl-3-bromopentane? which is right...

3) Also glucose can be broken down to produce alcohol, name this type of reaction.
I did fermentation
but the answers say Oxidation or redox
and then give the fermentation equation...Is that also right or something?

[Somye]

for number 2, its definitely 3-bromo-2-methyl pentane, always do functional groups in alphabetical orer

3- Was this from a trial exam- if it is, I would say yes fermentation would also be correct (if it was VCAA, then I guess not)

[destain]

It was and yes it might be wrong but just asking if it might also be called that maybe..

Just to confirm, reactions between alkanes and fluorine gas don't require a catalyst like alkanes and chlorine/bromine gas, right?

[destain]

Whats the catalyst for bromine gas?
and i don't think i've come across a reaction between flurione and alkanes .. LOL
and between isomers do physical AND chemical properties change or just physical?

[charmanderp]

Chemical properties too. For example only primary alcohols can be oxidised to give carboxylic acids, and tertiary alcohols can't be oxidised at all.

I think the catalyst for bromine gas is light as well.

what does hydrogenation do in a triglyceride

[soccerboi]

what does hydrogenation do in a triglyceride

converts the unsaturated fatty acid component into a saturated fatty acid

that split is definitely possible

3-bromo-2-methyl-pentane is right, always alphabetical order

fermentation is right lol, but the fermentation itself is an oxidation  but you should be able to say fermentation

You should really say oxidation, in bio 'fermentation' would be fine, but oxidation is more correct in chem

Pfft they'd call it fermentation in biochem That's chem!

Well that's not entirely true. Tertiary alcohols can be combusted and this is technically oxidation.

[charmanderp]

Touche.

[destain]

haha, would i be able to write on a vcaa exam, tertiary alcohols cannot be oxisdised at all?

so scared.........
