目標與任務[编辑]

此部教科書應於以下範疇成為同類教科書之典範,包括︰準確性、彈性、可用性及讀者聯繫工作。由於本部教科書經已發展成熟,讀者可隨時於網上查閱,亦可打印成讀本,更可自由發布。此外,讀者亦可僅費菲微甚或不耗分文而擁有一部最新且高質素大學級有機化學教科書,蓋其衍生品及其本身亦會維持自由、免費。當然,閣下亦可逕行自費付印成冊。

內容與貢獻[编辑]

以吾人所知,此乃全球首部獨一無二內容開放之有機化學教科書,而其編者亦會盡力改善本教科書直至冠絕群倫為止。此等改善過程一直於維基百科上行之有效,故吾人相信本書亦可為之。

本書內容均依據容許自由發布之許可證刊載,閣下可複製、編印、販賣及製作其衍生作品。惟閣下務須以易於複製及發布之途徑提供閣下所創製之衍生作品,猶吾人為爾所作。

本書含有連往敝網站伺服器外之網頁,凡非維基百科及其附屬網站刊載之內容均不予確保以同一許可證發布,然絕大部份亦非如斯。

導航系統[编辑]

英文維基教科書使用者Karl Wick對其於有機化學基礎概念及其子頁頂部添設連往上下一頁與各層頁面之連結、底部增設連往上下一課之連結,以及其他種種導航設施,表示滿意。其亦籲請欲提供協助者依此格式增設連結至其他頁面。

如何研習有機化學[编辑]

學生研習有機化學時碰到的一大難題往往就是要處理繁多資訊。而到了有機化學課程的第二個學期,更會學習超過一百個化學反應。故此,學生不單止要花時間組織處理這些資訊,更要花時間去明白和理解。雖然這有違大眾信念,但優秀的有機化學教授是會告訴你,你不需背誦有機化學的全部知識,反而你應該去理解它,明白它。那麼對比起你背誦的知識概念,你會運用得更好。

當你在書中見到任何事物,請切記問「為何?」,然後去搜尋資料,嘗試覓取答案。透過這個過程,你會不斷增加自己的學習經驗,而這些知識資訊亦都會「刻入」你的腦中。

每個人都有其最快捷且最不辛苦的方法去幫助自己學習有機化學,而這些方法或許有些微分別,但切記要用你自己認為最能夠幫助你的一個。不同的學習方法包括有使用閃視卡片、有機化學模型工具、群組學習、於黑板上抄寫化學反應等,又例如不斷上堂直至明白為止。

筆者建議購買一個有機化學模型工具,那你不但可以手持,旋動模型,亦能知道該份子於三維空間中是怎樣,把其型象化並記入腦中。

The writers would recommend to buy a molecular model kit so you can hold in your hand and visualize in your mind how the molecules look in three-dimensional space. If you can't get access to models or can't afford them, look online for sites that use the Jmol application or other rendering software that allow you to virtually rotate molecules.

It cannot be stressed enough that you must be able to visualize molecules in organic chemistry. The 3 dimensional structure of molecules often plays a crucial part in reactions. It can be the deciding factor in whether a reaction even happens, it can decide how fast it happens, and it can decide what the product(s) of the reaction is going to be. If you can't visualize the 3D structure, you won't be able to understand what's happening.

Sports analogy[编辑]

You can think of the different elements and functional groups as players in a game and the organic reactions as the plays. Just as each player or team has different strengths or characteristics and uses strategies to achieve what they want, organic chemists use the properties of each chemical to play off the others in order to achieve a desired end result.

Language analogy[编辑]

You can also think of organic chemistry like learning a foreign language. The atoms, for example, carbon and hydrogen and oxygen and nitrogen, are the letters of the alphabet. The structural theory of organic chemistry, namely, the tetravalencey of carbon, may be considered the essential underlying grammatical rule. All organic compounds are assembled under these grammatical rules, and may be considered words. The reactions of organic compounds may be perceived as the assembly of these words into sentences. A language analogy is also useful at this point, because the grammatical rules that control the assembly of sentences (formation of the products of organic reactions!) may be found in the study of organic reaction mechanisms.


Therefore, it is not necessary to memorize individual reactions. Overall patterns of reactivity become obvious when the mechanism of the reaction is investigated. Moreover, like any language, you have to practice it constantly. The more you "read" and "speak" chemical reactions and understand the mechanisms by which they proceed, the more fluent you will become. When you finish organic chemistry, you will literally be able to read, write, and speak in a foreign language. However, it is important to note that the language of organic chemistry is far simpler than any language people use for general communication! The words mean exactly what they mean, and the basic rules almost never change. But organic chemistry is far from a dead science. In fact, it is one of the most active and rapidly advancing areas in modern science today.

Research produces new knowledge, and the potential to formulate new rules. Perhaps you will make some of these discoveries, and future students will refer to your rules.
