想請問像這種題型該怎麼判斷呢？我不太知道要怎麼判斷分子的極性，還請各位幫忙～

2. Which of the following is the correct order for molecules from most to least polar?
(A) CHA > CF C12 > CF, H, > CCI, > CCI,H,
(B) CH4 > CF2H2 > CF, C12 > CCl4 > CCI H2
(C) CF,C12 > CF_H2 > CC12H2 > CH4 = CC14
(D) CF H, > CC12H2 > CF, C12 > CH4 = CC14
(E) CF,C12 > CF, H, > CC14 > CC12H2 > CH4

Answer 1

化工想轉化學系

這種先判斷結構,CH4、CCI4這種是最小的
再來可以判斷其它F跟H F跟Cl CI跟H的電負度差就可以比了~
