Organic 喺 DSE Chemistry 入面包含兩部份:

Part (I) Fossil Fuels & Carbon Compounds and Part (II) Chemistry of Carbon Compounds

​

這兩部份於 Paper 1B 佔分幾重:

• 2021 年佔   23.8%  (20/84)

• 2022 年佔  21.5 %  (18/84)

• 2023 年佔  17.9%    (15/84)

而且同 Paper 2 elective 部份內容又有關, 所以兩 Part 讀唔通的話, CHEM 就難考得好。

我們就先由較易嘅 Part (I) Fossil Fuels & Carbon Compounds 入手啦! 留意這部份有5條 Concept line。

​

Part (I)  嘅5條 Concept line 係:

1.  Hydrocarbons from petroleum

2.  Chemistry language for hydrocarbons

3.  First hydrocarbon family found in petroleum – alkanes

4.  Second hydrocarbon family formed from cracking of alkanes – alkenes

5.  Environmental problems associated with burning of fossil fuels

  

我會每星期按以上次序分享1條 Concept line 嘅有關 Core Concept (核心概念), 同埋有咩 Exam-type Qs (測考題型), 仲有有用嘅網上學習資源；希望剛學完這 TOPIC 或者開始大溫習嘅同學跟住嚟澄清 Core Concept 和練做 Exam-type Qs, 應該會幫到你攞到較好成績。
