Chemistry: Post your doubts here!

ok so what you basically say is that since you need to only slightly oxidize an alcohol to an aldehyde you need a weaker oxidizing agent?
because if its stronger like KMnO4 it'll oxidize it directly to carboxylic acid? right? did i get it right?

similarly if i use LiAlH4 it'll convert an acid to alcohol, while nabh4 will turn it into an aldehyde?

This AS and A Level questions in the same topic seems very unhealthy to both parties.

Does a liebig condenser or a U tube have any size or capacity? no right?

Isn't it all about the oxidising agent (whatever it may be) being in excess?

If i fail, i'll just wait for you to pass AS and then i'll ask u all the questions i want if i repeat next june (MAY ALLAH FORBID)

JEEEZ-.- WHY IS THE CHEMISTRY SYLLABUS SO LONG AND DIVERSE.. you can't remember both Organic and Inorganic at the same time!

tell that to the cursed examiners
They'll listen to you

Maybe we should make a new thread specifically for P2 and later one for P4?..

yesss plzz do that!! :O
i think i'm gonna sit for P4 too!! with the questions i have seen .... P2 is hell enough as it is!! tag me if u make that thread plz =)

urrgghh ikr!! :O
i am still stuck on the organic!! there are just so many conditions and like a 100 reactionsss x-x KMN!! X__X

If I get less than 55 in this theory paper.. then my A is long gone.. I really suck at practicals .. and MCQs are well :\ so this paper is where my A lies in ..

AND WORST OF ALL.. I have GP tomorrow.. for which I have studied nothing.. haha

oh crap!! I hate CIEE X__X hadd hai yaaar!! :O :O :O
itnaaaa saaaaaraa syllabus hai.. they shud've given us more time for chem!! :O :O :O
Best of Luk for ur GP and Chem buddy... gosh that sucks :O

Keep high hopes guys... it's all about having faith.. Duaa is the strongest of things....

I have Biology and Mechanics on the same day, 13th May.

 

[daredevil]

okay question: - give me the formula of Tollen's reagent
it is [Al(NH3)2]+ ??

ohhh myy....
but at least u have 3 days holz before it ryt??
