[學習] 什麼是離域化(delocalization)
各位板上的大大
大家好
我是看到有機化學課本中
(Organic Chemistry With Biological Application 2nd,John McMurry)
一段文字有關於Carbonyl group 酸度的比較
When a hydrogen atom is flanked by two carbonyl groups,
its acidity is enhanced even more
他提出的解釋
This enhanced acidity of beta-dicarbonyl compounds
is due to the stabilization of the resultant enolate
ions by delocalization of the negative charge over
both carbonyl groups.
他下文有舉例因為擁有兩個carbonyl共振的型態較多
因此較穩定
也因此較酸
說了那麼多
我只想問delocalization是什麼@@?
他跟共振有關傒ㄇ
如果我太鑽牛角尖了，或問題太蠢
請多多包涵
