important theory qn
for alkaline hydrolysis of amide, let's say for example, there
are 4 amide linkages in a cpd. is it 4 moles of NaOH will react
with the cpd?
or is it 8 mol of NaOH? Angeline and jasmine writes NaOH will
react with the COOH formed from the alkaline hydrolysis of
amides.
is it straight away will from COO- liao instead of COOH then
COO- , as suggested by Angeline and Jasmine?
i havent encountered this in all books and notes so far, except
in the solution written by A&J. seems like they are the first
few who thought of this
"Angeline and jasmine writes..."
Wah seh, intimate first name basis leh, machiam they ur
ex-girlfriends liddat...
Instead of spoon-feeding you the answer (and I don't like it
when you openly criticize/point out the author's typos on the
forum, even though in your mind you think you're doing them a favor
by pointing out their typos ; or worse, when you ask *me* to
publicly confirm who's right who's wrong, eg. Chan Kim Seng vs
George Chong vs CS Toh etc), so I'll leave it to yourself to solve
this problem, quite easily done, by drawing out the hydrolysis
mechanism (try drawing both acidic vs alkaline mechanisms), and
you'll get your answer.
And don't post the answer here on the forum (as you are wont to
do). Anyone else interested can go draw out the mechanisms for
themselves to arrive at the answer.
idk if its typo
i am asking becos i dunno the chemistry concept, not becos i am
questioning their typo
im not and never my intention to criticise authors. my
words never show that. i am asking qn. but if other people
interpret in that way, let them be. i never write anything
offending, and my words not against law
Fair enough, I meant you "criticize/point out the author's typos",
rather than criticize the authors themselves (I'll go edit my
previous posts to be fair to you).
Regardless, like everyone else who asks me Chem qns here on the
forum, I'd rather you focus on asking about TYS or Prelim Papers
qns, instead of comparing notes and books and narrowly zooming in
on nitty-gritty details and OCDing over who's right who's wrong
(which you can actually settle yourself by cross referencing and
applying common, ok, chemistry sense).
OCD ppl like me like to learn true knowledge, after learning
many wrong concepts/knowledge/things all my life(i dont blame
anyone) , I am Tired of learning false and wrong concepts, i only
desire to learn the Truth.
i work extremely hard cross reference excessively, think,
analyse, and then if truly in need, seek help and the Truth from
one of the rare and true teachers, Ultima.
self discovery and learning and independent learning is
supremely important (must put in effort think critically yourself
first before asking) , with the guidance from extremely
Trustworthy, knowledgeable, credible educators like BFJC
yes i truely thank all the authors who write these books to help
me gain knowledge ,and i love all these books they wrote, they are
great books i treasure them
Love the Sciences , work hard to learn the Truth
It's all well and good you passed your Prelims, but remember you're
up against the best of the entire Singapore cohort of all 22 JCs.
From now on, imagine yourself taken out of your school and thrust
into RJC. That's who you're up against in the bell-curve. *evil
laugh*
PS. The message above is directed at all Singapore JC students
taking the 2016 A levels. Have fun! ;Þ
Yes, i settle for myself, for the alkaline hydrolysis of Amides,
one mol of OH- will react with 1 mol of amide, forming the
Carboxylate immediately.
Correct?
i drew the mechanism with help of made easy org book page 365(
Thank you, George Chong), and the help of Google, and i realise the
Carboxylate is formed(i.e. not carboxylic acid form then
Carboxylate) , in alkaline hydrolysis.
Eh hello I told u liao, whatever conclusion you get, don't post on
the forum! Don't spoil the fun for others! Encourage them to draw
out the mechanism for themselves to get the answer for themselves!
Therefore, I will neither confirm nor deny your
finding.
