Chemistry P22 Questions

[farjadrenaline]

Difficult question on acidic oxides . oxidation number question .
other question : energetics activated complex theory
extraction of Al , fully 1question on it
organic : dnph test mechanism for carbonyl group and how to differentiate
other organic question on alkyl halides and acyl chlorides
almost confirmed from a reliable source.

hey man thanks alot..... our school teacher made a guess paper almost like urs.

 

[farjadrenaline]

yea man i've been given this and guess and it completely fits the trend of papers aswell

 

[blue berry]

'' activated complex theory'' what is that?

 

[makko]

'' activated complex theory'' what is that?

its related to the complex formed at the peak of an energy profile diagram which decomposes into the product molecules

 

[john_smith]

acyl chlorides are not evn in da AS syllabus!!!!

 

[ashhadazam]

@abv.
Exactly !!! we hav studied acyl chlorides only in esterification !! nothing else

 

[makko]

react pcl5 with a corbonate ul get acyl chloride.RCOCL is an acyl chloride just like pcl5 with an alcohol.

 

[intel1993]

so activated complex theory' it is frm AS or A2..........????

 

[farjadrenaline]

@intel1993 : It's in AS , but the whole theory is not given just the fact that it has something to do with the energy profile diagram . If they give the question based on it ,they will provide with sufficient info about the theory .... hope that helps

 

[intel1993]

ok thnx.................!!!

 

[makko]

what is dnph mechanism ? i knw dnph result with ketone or aldehyde.

 

[intel1993]

no mechanism but only the reaction is required and observation

 

[makko]

oh ok thanks...
