Homework Help: chemistry

Posted by lyne on Tuesday, May 5, 2009 at 10:42pm.

my teacher told me that polar bonds have a difference in elecronegativities of .4-2.1

is that the only way to find if a bond is polar?

also how would you find out if the MOLECULE is polar or not?
- i think i remember my teacher saying something about dipole moments...
