Chemistry Paper 4-theory- doubts =D
ahaa i don't havw that sorry but check momo's post above she posted it -
Chemistry and Physics some Keypoints/Notepoints (onDemandOnly) !! :)
reaction WITH phenols but not reactions on how to prepare phenols from benzene -
Chemistry Paper 4-theory- doubts =D
can u pls tell me what is in this application booklet? -
Chemistry and Physics some Keypoints/Notepoints (onDemandOnly) !! :)
now who is right? -_- cuz i never saw such a reaction in the books :S -
Chemistry Paper 4-theory- doubts =D
do u mean the databooklet ? the one we get in the exams ? -
Chemistry and Physics some Keypoints/Notepoints (onDemandOnly) !! :)
is this in our books? :o -
Chemistry and Physics some Keypoints/Notepoints (onDemandOnly) !! :)
railey check this thread out for chemistry topics doubts if u haven't seen it yet... -
Chemistry Paper 4-theory- doubts =D
you can print it..it is found in the last part of the syllabus -
Chemistry and Physics some Keypoints/Notepoints (onDemandOnly) !! :)
this isn't in our syllabus..where did u get this question from ? :S -
Chemistry and Physics some Keypoints/Notepoints (onDemandOnly) !! :)
haha maybe :P anyway really if u got stupid questions its okay ask me..i would say what a stupid question and make fun of u in my mind but its not bad to ask any question though ;) -
Chemistry and Physics some Keypoints/Notepoints (onDemandOnly) !! :)
hahah well the question u asked was really stupid :P but its okay a scientist once said ask everything even the most stupid questions u got if u want to succeed ;) -
Chemistry and Physics some Keypoints/Notepoints (onDemandOnly) !! :)
not good at all haha but come on i am using touch pad! not even a mouse so its pretty difficult to explain it and the worse part is it has been explained already before i post -_- so wasted my time drawing shit -__- -
Chemistry and Physics some Keypoints/Notepoints (onDemandOnly) !! :)
shhh dont embarrass me :rolleyes: -
Chemistry and Physics some Keypoints/Notepoints (onDemandOnly) !! :)
here i attached the mechanism but as always excuse my shity drawings :P see there is a dipole on the carbon and oxygen in the c=o bond as u can see..the lone pair in the CN will attach the positive dipole on carbon and will form a C-CN bond this will leave a negative charge on the oxygen... -

whaaaat?!! come onnnnn from what i said above u should be able to do this question with closed eyes just use the formula F = Le F = 96 485 and e = 1.6022 x 10^-19 L = 96 485/(1.6022 x 10^-19) L = 6.0220 x 10^23 PROVED!! got it now ? -
Chemistry and Physics some Keypoints/Notepoints (onDemandOnly) !! :)
see u just need to know the formula F = Le where F is the farady constant, L is avogadro's no and e is the charge of one electron. it is used to prove avogadro's no thats it...
