I did say second option was correct ^^
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

As far as I have read.dun u think!! elimination is more than substitution u told :'|
elimination = dehydration my teacher said me once :'| it creates double bond no? :'|As far as I have read.
Elimination . Is the removal of two substituent from an organic compound
and in Substitution only single substituent in removed.
It relates to SN1 and SN2 mechanism .
Elimination removes two units while dehydration removes only Hyrdrogen.elimination = dehydration my teacher said me once :'| it creates double bond no? :'|

What does this part of the chemistry syllabus means? "(h) show understanding of, and use, the Brønsted-Lowry theory of acids and bases, including the use of the acid-I, base-II concept"
What's the acid-1, base 11 concept means?
People .. is this answer , the same as mine ?

Q5 c(ii)
marking scheme : >CO or carbonyl absent
my answer : It is not ketone .. (ketone absent)
At last .. Is carbonyl the same as ketone ?

no. H2 and Ni only reduces Alkenes to alkanes
btw check this image. I found it in a doc. It summarizes which and what get oxidize and reduce.

i didn't know that H2 and Ni reduce CHO but the markscheme of s13/21 says so.no.. i said that H2 n Ni reduces both alkenes n carbonyl compounds... n u said that they only reduce alkenes...
KMnO4 can oxidise CHO in the presence of H2SO4....i didn't know that H2 and Ni reduce CHO but the markscheme of s13/21 says so.
but how is it possible that POTASSIUM PERMANGANATE CAN NOT OXIDISE CHO into CO2H? that is not possible. this oxidising agent is an EXTREMELY powerful reagent. and it will oxidise almost everything. if very concentrated and heated it can oxidise all Carbons and hydrogen in any organic compound into CO2 and H2O. i believe this is another time CIE is wrong. first time being that elimination occurs in alcohol.
KNoO4 can oxidise everything that any oxidising agent can. and obviously in presence of H+ ion.KMnO4 can oxidise CHO in the presence of H2SO4....
lol n KMnO4 cn only oxidise aldehydesKNoO4 can oxidise everything that any oxidising agent can. and obviously in presence of H+ ion.
CIE gone mad
i am talking after reading research papers from top universities including university of new york.lol n KMnO4 cn only oxidise aldehydes
it must b just to keep everythng simple for our age group... they knw everythng mch better thn us...
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
