3F：推 CHHO:可是B说hydrogen bonds between water and oil molecules 01/24 09:49
4F：→ CHHO:他们之间没有氢键阿~~ 01/24 09:50
5F：推 Obiwang:碳上的氢是有可能有氢键的... 01/24 11:18
6F：推 CHHO:HCN 好像就是个例子,但"oil molecules"想不出什麽例子...OTZ 01/24 14:02
7F：推 IboNySun:(大惊)楼楼上是说油上的碳和水间可能有氢键?? 01/25 01:03
8F：推 Obiwang:我不确定耶...碳氢化合物如果有dipole moment算不算阿？ 01/26 09:43
