the electronegativity difference makes the bond polar and it is NOT symmetrical Br-F has two distinct ends and the F end is more negative O=C=O is symmetrical and even with polar bonds it is non polar that goes for CF4 also. was told if its symmetrical its not polar. I could understand if H-H is no polar but what about Br-F or even CH3 Are they polar or non-polar. Update: Is it right I use electronegativity by saying F is more negative so the molecule is polar..but their symmetrical. Follow.
