覺得答案怪怪的 Comparison of boiling points: a.due to van der Waals forces, isopentane has higher boiling point than n-pentane. b.due to hydrogen bonding, p-nitrophenol has higher boiling point than o-nitrophenol. c.due to electron donating property, butanamine has higher boiling point than butanol. d.due to molecular weight, butyl propanoate has higher boiling point than propanoic acid. 答案為b 我覺得d才是對的吧 兩者都有H-bond, 所以比較分子量對嗎? 謝謝勒 -- -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.60.5.250

o-nitrophenol有分子內H-bond 相對分子間較少

另外 butyl propanoate是丙酸丁酯 沒有氫鍵吧...

就算沒有空格 丁基丙酸應該不符合命名原則

應該是逼阿~六環的分子內氫鍵
