Alkenes and Addition Reactions
課 型
理論新授課
A-level Syllabus(A-level 教學(xué)大綱摘要)
1. explain the shapes and bond angles of ethene in relation to s and p carbon-carbon b
3、onds
(用s 鍵和 p 鍵的知識來解釋乙烯分子的鍵角與分子構(gòu)型)
2. describe geometrical isomerism in alkenes, and explain its origin in terms of restricted rotation due to the presence of p bonds
(用π鍵旋轉(zhuǎn)受阻的理論來解釋烯烴中存在幾何異構(gòu)體的原因)
3. describe the chemistry of alkenes as exemplified, addition of hydrogen, steam, hydrogen halides a
4、nd halogens
(以烯烴與H2、H2O、HX的反應(yīng)為例,來描述烯烴化學(xué))
4. describe the mechanism of electrophilic addition in alkenes, using bromine/ethene as an example
(以溴與乙烯的加成反應(yīng)為例,描述烯烴的親電加成反應(yīng)機理)
5. Markovnikov’s Rule 、Carbocation Stability
(馬氏規(guī)則、碳正離子穩(wěn)定性)
重點與難點:
1. 烯烴的結(jié)構(gòu)特征:π鍵的形成和特點;順反異構(gòu)的形成條件
2. 烯烴的不對稱加成:馬氏規(guī)則、碳正離子
5、穩(wěn)定性
教學(xué)實施手段:
講授、角色扮演游戲、討論、提問
