Question
Which of the following carbon-halogen bond is extremely polar though nonionic among given alkyl halides?
✓

Answer

  1. C−F
Explanation:
C−F bond is extremely polar because Flourine is most Electronegative atom (E.N = 4.0) so the E.N difference is more for carbon and Flourine.
Polarity order: C−F>C−Br>C−Cl>C−I.
