As far as i know a change in pressure does affect the equilibrium position when there are gases involved.....an increase in pressure favors the side with fewer moles, so in the case of methanol i think the products side was favored.....it is only the equilibrium CONSTANT that is not affected by a change in pressure...

yup temperature increase, decreased the yieldBingo!
Increasing the temperature decreased the yield and the catalyst had no effect.
What did you get your percentage purity as?

whoa man! ditto! i did exaaaactly the same thing!
found the moles of X and of H atoms...
i dunno:s i guess it's okay goes i think they do consider the what u've written if it resembles and is pronounced like the original terminology.....not very sure though:/
Q4 last part the cyclohexene didnt get oxidises to carboxylic acid..this was a tricky question since the carbon is attached to 2 other methyl groups so it would be oxidised to a ketone, instead.

So is it an acid or ketone? :shttp://wwwchem.uwimona.edu.jm/lab_manuals/c10expt12.html
Yes, chemistry can be a troll sometimes.
Now you know why we worry about stuff that gets you '2-3' marks.
The link says it acid but we have studied that a secondary alc is oxidised to a ketone lol.. -___-http://wwwchem.uwimona.edu.jm/lab_manuals/c10expt12.html

There's the confusion.
do uk if the high pressure increase yoeld or decrease it?There's the confusion.
Even though, 2 secondary alcohols DO form (in the intermediate), the bond between the two carbons which bear the alcohol functional groups breaks. This makes them primary alcohols which are then oxidized to aldehydes and further heating oxidizes the aldehydes to carboxylic acids.
Oh well. AS Chemistry is overrrr for me!
I suppose it would increase it. That's what I wrote.
No, you only lose marks if you misspell an actual chemistry term, for example writing "chlorine" instead of "chloride". Electrophillic is something minor so I highly doubt you will lose a mark there.
no its doesnt form a ketone at all, all cyclics alkens form carboxylic acids when oxidised
obviously increase as it depends on where there are less no. of moles which was in the forward direction i suppose
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
