15 days left to the most major exam of 2008. I think I'm only 50% prepared.... this is very discouraging. Well... today I went back VS, wanted to claim my testimonial, but it wasn't time yet for the General Office. After that I went to Parkway with my juniors and I forgot to return back to VS.... LOL! I gave a private tuition to my junior.... on Organic Chemistry and a wee bit of Physics... I thought it was quite succesful. I have high hopes for my friend. I'm very sure he have the ability to enter VJC... GOOD LUCK REUBEN SU !
Learnt something new (or not): Another way of testing for alkenes other than bromination is by adding aq. alkaline potassium permanganate, whereby the purple hue will fade to colourless.
Come to think of it.... We've learnt that oxidation of alkenes by cold alkaline potassium permanganate will yield diol.... and the potassium permanganate is reduced... hence it explains the decolourisation. =)
