about the latest CE syllabus for chemistry

Question

我想問吓:

1
catalytic de(hydration)係咪 許ce chem syllabus 裡面的一部份?
點解我好似冇學過咁o既?

2
hydrogenation 呢?

Answer 1

1. actually, it is just adding concentrated sulphuric acid to the solution and heat it.

2. hydrogenation is the addition of hydrogen to usually C-C double bonds, with the use of catalysts, such as nickel, platinum etc., hydrogenation of C-O double bond is also possible, but needs much more drastic condition, ofcoz with the presence of the catalysts mentioned above.

for the lastest syllabus, u can check it up in HKEAA's official website.
