Chemistry paper-21

[1357913579]

how was the paper?
what do u think would be the gt?

 

[HubbaBubba]

Asked people what they thought of the exam, most thought it was good to easy. I suppose the curve would be high, around 47-49/60 for A

 

[muzzaml]

I think it was really easy, as did most around me... I'm not an expert so far as predicting GTs, but I would expect it to be really high compared to the last few years.

 

[FRENZYAMU]

It was wayyyyyy too easy, felt like an o lev paper,,,,,but now the other papers will come hard since it was impossibly very easy, it had NO equilibrium questions !,

Guys, in the first table. Did the 3rd column say "Conditions" or "Reagents" ?

 

[no.mercy]

Threshold is going to be around 48.

Pretty sure it said reagents

i dont wanna know if what i will say is discussing a paper or not. if it is please tell me and i will delete my post because i am not willing to discuss but i just have a general question.

if we use hot acidified MnO4 on a double bond which had RCH=CRH it will oxidise to carboxylic acids? if i only oxidized it to aldehyde do i lose marks for that or both are accepted ?

in the book it says it first gets oxidised to aldehyde and then Carboxylic acid so i dont think they will deduct marks

is there ecf on MOLES AND DOES ANY BODY KNOW THE TOTAL MARKZ FOR WHOLE QUESTION 1

 

[Mariam Mohamed SX132]

well I only know the calculation plus equation part was 9 marks!

 

[Muhammad TAimoor]

It was of 11 marks altogether, question 1. I hope its not paper discussion.. no intention of that

 

[Mariam Mohamed SX132]

haha its just mark discussion dont think that's cheating

 

[Muhammad TAimoor]

Yeah..*sighs*

 

[Manobilly]

It was for 11 marks the whole question.

 

[Mariam Mohamed SX132]

Yeah..*sighs*

wanna discuss it in private?

 

[Mashfiq]

So that a no on the ecf? :/

 

[Mariam Mohamed SX132]

I think it is an ecf! cuz each one is related to the question before it!

 

[scarface007]

12 marks if im not mistaken and there will be ecf, there is on most of the moles questions

 

[red_angel]
