Assalamu Alaykum AS and A2!
i just figured out that our Chemistry textbook had some errors
So, i would like you to follow this link and make sure you read the whole page because it is very important. I'm very sorry for the AS fellows because they had their paper 2 long ago.. but maybe u can do p4 and p5 better next year Good Luck!
As for A2, the thought of only getting to know this a week b4 our p4 is very scary. With all due honesty, I have absolutely no words to calm you down as i myself am suffering from a "close-to-a-heart-attack" stage....

AS students didn't get affected by that since the only very minute errors.. Honestly I have that book but I rely on my teacher's notes rather than the book and that has proved to be the best thing to do

thank you

Because it's not excess Cl2. Although the second -CH3 would not really come to my mind....anyone has an alternative thought on why the second one might not react? Personally, that's the explanation i'd give to myself, that the Cl2 is not in excess... have u read the examiner's report? I'll read it right now and let u know inshAllah

 

[knowitall10]

Silent Hunter Brother, i just read the examiner's report and it doesn't say anything. It's along these lines: A significant number of students were able to do it.
So yeah...I hope my explanation satisfies you.... If anyone else has a different view, please inform us, tag me and silent hunter. it's a good question, i'd like a sensible explanation too
Jazakum Allahu Khair

ASSLAMU ALAYKUM WA RA7MATULLAH!!!

NOTE: THE CHEMISTRY APPLICATIONS BOOKLET SUCKS BIG TIME AND HAS BEEN PROVEN SO BY THE CHEM GUIDE SITE. PLEASE REFER TO THAT SITE FOR THE LAST FEW CHAPTERS AFTER ORGANIC BECAUSE IT IS PRECISELY TO THE POINT AND ACCORDING THE CURRENT SYLLABUS. THE MORE MISTAKES THE GUY POINTS OUT, THE CLOSER I GET TO HAVING A STROKE. IT'S VERY IMPORTANT!!!
Thank you.
May Allah Help us lead the path of Righteousness
