    Germsai 兄的答案是正確的

    圖片參考:http://www2.latech.edu/~hji/org252/03mar14/imageV2...

    http://www2.latech.edu/~hji/org252/03mar14/imageV2... 首先醚中的氧之孤對電子與HI 的質子結合2. tert-butyl group 與氧的鍵會斷 因產生穩定的三級碳陽離子 因而釋出一級醇 (本題是 CH3CH2OH)3. 三級碳陽離子可與 I- 進行 SN1 反應得 tert-butyl iodide 也會有E1 脫去反應 得烯

    嗯..你的答案對..一時以為這是一個SN2的反應...其實應該是氫離子(H+)先接在醚的那個O上的孤電子對...才對..( CH3 )3COCH2CH3 + HI -------( CH3 )3CI + CH3CH2OH
