标题[问题] about boiling points
时间Fri May 16 14:24:04 2008
觉得答案怪怪的
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.
答案为b
我觉得d才是对的吧 两者都有H-bond, 所以比较分子量对吗?
谢谢勒

1F：推 joety1103:o-nitrophenol有分子内H-bond 相对分子间较少 05/16 15:50
2F：→ joety1103:另外 butyl propanoate是丙酸丁酯 没有氢键吧... 05/16 15:51
3F：→ joety1103:就算没有空格 丁基丙酸应该不符合命名原则 05/16 15:52
4F：→ anarchyalu:应该是逼阿~六环的分子内氢键 05/20 10:25
