2. 要溫熟cracking process(裂解過程)、reaction condition(反應條件)、equation(方 程式)同埋e個reaction advantages(反應嘅優點) 。睇睇下面嘅pastpaper:
1999 Paper I 9b
2003 Paper I 7b
2003 Paper I 7b
2005 Paper II 2
3. 記住各種pollutant(污染物)嘅cause(成因)、reducing method(減少方法)同埋 effect on human and environment(對人同環境影響) (注意呀increasing height of chimney (增加煙囪高度)係唔可以減少空氣污染)。 睇睇下面嘅pastpaper:
1999 Paper I 3

1999 Paper II 30
2001 Paper II 14
2003 Paper I 1b
4. 注意alkanoic acid(烷酸)同埋ester(酯)嘅關係,它們只係有相同嘅molecular formula(分子式),佢哋係唔同類型嘅compound,有唔同嘅reaction同埋 physical properties(物理性質),例如 b.p.
