Studied by 47 peopleWhat does A represent?
the center atom
What does X represent?
atoms bonded to the center atom(ligands)
What does E represent?
lone pair of electrons around the center atom
Planar molecules are…
generally flat and nonpolar
If a molecule has all of the same ligands…
it will be nonpolar
If there is a lone pair on the center atom…
it is polar
If the ligands are different…
it will be polar

AX polarity
have to find the difference in electronegativities to determine the polarity
AX angle measure
no angle measure because there is no true center atom
