Hi there,

I know it is my first post but I was hoping someone can help me with the following question. I've got an exam tomorrow and am struggling to understand this one.

I've copied the question directly from the paper...

_______________________________________________________________________________________

The table below gives information about the attraction some atoms have for bonded electrons.

Atom       Attraction for electrons
   C                   Least
   I                       i
   Br                     i
   Cl                      i
   Fl                  greatest


Which of the following bonds is the LEAST polar?

A.   C-F
B.   C-Cl
C.   C-Br
D.   C-I

_________________________________________________________________________________

Hope someone can help.

D is the answer. Check the difference in electronegativity of the two atoms and the least difference gives you the least polar molecule

Thank you both for your help. I understand it now.
