    Bio 42 2015!!!

    I don't see the point over arguing about this :p Bottom line The Second cross was obviously necessary to show without any doubt. The first cross may also carry some marks. But even if it doesn't you won't lose marks for drawing the first cross aswell.

    Bio 42 2015!!!

    The second cross was obviously necessary to show it'll carry the most marks. But i think you most probably need to show where did the Genotype of the Parents of the second generation come from. Like what geneotype did the parents of the first generation have etc. You needed to show that both...

    Bio 42 2015!!!

    No the question didn't EXPLICITLY ask to draw the second Generation only. Don't go on saying stuff like that. It doesn't matter how many crosses you make. You just need to get your point across

    WTF CHEMISTRY PAPER 42 IS SO HARD

    This is what I first thought too but the key word was COLD HCl and COLD NaOH. Hydrolysis does not take place without heating in esters and amides

    WTF CHEMISTRY PAPER 42 IS SO HARD

    No I'm not. Amide is neutral in nature that doesn't react with either NaOH or HCl. But considering phenols acid nature it will react with NaOH.

    WTF CHEMISTRY PAPER 42 IS SO HARD

    You'll most probably get marks if you wrote the correct functional groups not bothering about the molecular formula. or let's you say you don't get a mark for that.. you'll still get an ECF for drawing the structures according to your own functional groups. Of course provided they match the...

    WTF CHEMISTRY PAPER 42 IS SO HARD

    Amide+ Acohol (insoluble in both) Amine+ Carboxylic acid ( soluble in both ) Amine+Ester ( Solubile in HCl and Insoluble in NaOH) Amide+ Phenol ( Insoluble in HCl and soluble in NaOH) am i right guys

    WTF CHEMISTRY PAPER 42 IS SO HARD

    Dude i get how the paper was good for you and all. But I doubt the threshold will be around the range you said. You should learn to help other people not go on demoralizing and boasting how good your paper went..

    Those parts were easy :p EDIT: The functional groups and structures were tricky but im sure there will be more than one right answer for each compound and structure

    WTF CHEMISTRY PAPER 42 IS SO HARD

    It's not harder than previous year ones. The previous years had questions way worse than what this had. As for organic it was tricky but was for like 8 marks. Expect A to be around 63 atleast.
