那一個是油和水不能混合的原因
(A)The water molecules cannot break the London forces between oil molecules
(B)the hydrogen bonds between the water molecules are stronger
than the hydrogen bonds between water and oil molecules
(C)the London forces between water molecules are not as strong as the
ones between oil molecules
(D)the hydrogen bonds between the water molecules are hard to break by
oil molecules
(E)thr oil molecules are lighter than that of water molecules
謝謝各位~~

2F：推 achernarsw:複選題嗎?，如果是的話我選BC 01/24 09:14
3F：推 CHHO:可是B說hydrogen bonds between water and oil molecules 01/24 09:49
4F：→ CHHO:他們之間沒有氫鍵阿~~ 01/24 09:50
5F：推 Obiwang:碳上的氫是有可能有氫鍵的... 01/24 11:18
6F：推 CHHO:HCN 好像就是個例子,但"oil molecules"想不出什麼例子...OTZ 01/24 14:02
7F：推 IboNySun:(大驚)樓樓上是說油上的碳和水間可能有氫鍵?? 01/25 01:03
8F：推 Obiwang:我不確定耶...碳氫化合物如果有dipole moment算不算阿？ 01/26 09:43
