關於油和水的混合

[GOPOL (爬不起來阿!!)]

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~~

→ mobisrat:(E) 也因此在無重力下 油和水可混合
推 achernarsw:複選題嗎?，如果是的話我選BC
推 CHHO:可是B說hydrogen bonds between water and oil molecules
→ CHHO:他們之間沒有氫鍵阿~~
推 Obiwang:碳上的氫是有可能有氫鍵的...
推 CHHO:HCN 好像就是個例子,但"oil molecules"想不出什麼例子...OTZ
推 IboNySun:(大驚)樓樓上是說油上的碳和水間可能有氫鍵??
推 Obiwang:我不確定耶...碳氫化合物如果有dipole moment算不算阿？
