Does the issue of having three elements combined in a molecule change the electronegativity calculation?
Concerning the molecule CHCl3
The difference between C and H is 2.4-2.1=.3
The difference between C and Cl is 2.5-3.0=.5
The text book offers no examples of this situation for me to go on.
I think that all the bonds should be considered polar covalent or is there and exception I need to be aware of?
How do determine the polarity of the molecule? From what I've read it leads me to believe that is would be a polar molecule, am I correct?
