好人甲 10 Posted November 6, 2010 Report Share Posted November 6, 2010 下列有機物的碳碳單鍵鍵長何者最短a)H3C-CH3b)CH2=CH-CH3c)CH2=CH-CH=CH2d)HC≡C-CH3e)HC≡C-C≡CH請問...都是單鍵要怎麼比較呢? Link to post Share on other sites
Shih 10 Posted December 27, 2010 Report Share Posted December 27, 2010 Ans :(a) CH3-CH3 最短(b)©(d)都有共振現象，電子雲平均分配於碳碳間，鍵長均大於單鍵 Link to post Share on other sites
jessti 10 Posted December 27, 2010 Report Share Posted December 27, 2010 你說的對只是答案正好反過來e最短Ans :(a) CH3-CH3 最短(b)©(d)都有共振現象，電子雲平均分配於碳碳間，鍵長均大於單鍵 Link to post Share on other sites
