2015 A Level H2 Chemistry Paper 1, 2, 3

In this case, for q2 will they accept B or D? Coz I know there's a question which accepts 2 answers for last year p1.

May or may not, Cambridge examiners will discuss this amongst themselves and the Chief Marker will make a decision.

Whats hybridised and unhybridised orbitals?

Hybridised means formed bond alr, unhybridised haven't?

For qn 21 , i identified pentyne , pent-2-yne, 3-methylbut-2-yne, 3 methylbutyne

Which one of my identified structural isomer(s) are wrong?

Go Google, Wikipedia and Khan Academy "orbital hybridization" lor.

3-methylbut-2-yne doesn't exist, coz your C atom's octet kena violated.

Hi thank you so much for doing this! Really appreciate it! :)

May i know what is minimum % to get A for H3 pharm. chem? As in what is the traditional boundary? Just had my paper today and it was easier than past yr paper. Really scared that i will get bell-curved by all the zai ppl out there. Thank you once again!!

Your sincerely

For H3 Chem there won't be any significant bell-curve moderation, as being much tougher to get the Distinction grade (in spite of the fact that only the best students of every cohort take H3 subjects), there won't be significant Distinction grade-inflation and thus little need for moderation. So you can regard H3 Chem grade boundaries as unmodified, no worries.
