標題[問題] about boiling points

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

1F：推 joety1103:o-nitrophenol有分子內H-bond 相對分子間較少 05/16 15:50
2F：→ joety1103:另外 butyl propanoate是丙酸丁酯 沒有氫鍵吧... 05/16 15:51
3F：→ joety1103:就算沒有空格 丁基丙酸應該不符合命名原則 05/16 15:52
4F：→ anarchyalu:應該是逼阿~六環的分子內氫鍵 05/20 10:25
