I agree with Mohammed, I think it was pretty damn hard. Well I suppose it depends on what you are aiming for. If you just want a B or C, it's probably really easy. I am aiming for an A*. I think I did relatively well though. What do you think the grade boundary for A will be this year? 40/80? 45/80? 50/80?

Can someone tell me the answer to

1) Which of the acid reaction is the redox reaction and the reason? (Li + HI), (Zinc Carbonate + HI) or (the one with MgO)
2) Which carboxylic acid forms when acidified potassium manganate react with Butanol? and its structural formula?

For your info, I choose:

1) One with MgO, as oxygen is involved (the explanation probably wrong) :)
2) Butanoic Acid, CH3CH2CH2COOH

Can someone confirm? :)
